- How do plants store energy from sunlight in foods we eat, like fruits and roots?
Answer: as chemical energy in sugars and starches
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. When plants capture light energy from the sun, they don't store it as light—they transform it into a different form of energy that can be stored. During photosynthesis, plants use light energy to make sugar (a type of food). The sugar molecules store the energy in their chemical bonds—this is called chemical energy. Different plants store this energy-rich food in different places: lettuce stores it in leaves, carrots store it in roots, potatoes store it in underground stems, apples store it in fruits, and corn stores it in seeds. Choice A is correct because it accurately describes that plants store energy as chemical energy in sugars and starches. This demonstrates understanding that energy is stored in a usable form (food molecules) in various parts of the plant, and that the stored form is chemical energy, not light or heat. Choice C fails because it states energy is stored in water, when water is used in photosynthesis but doesn't store energy. Energy must be stored in a stable form that can be used later—sugar and starch molecules store energy in chemical bonds, not in water, chlorophyll, light, or heat. To help students understand energy storage in plants: Use food examples they eat—potato (stores energy in underground stem), carrot (stores in root), apple (stores in fruit), corn (stores in seeds), lettuce (stores in leaves). Ask: 'Where did the energy in this carrot come from?' Trace backwards: 'Energy in carrot ← made by carrot plant ← using sunlight ← sunlight came from sun. So the energy you get from eating a carrot originally came from the sun!'
- The model says leaves capture light energy; plants store it by making what?
Answer: sugar that can be turned into starch later
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. When leaves capture light energy during photosynthesis, plants use this energy to make sugar molecules. The sugar contains the energy in its chemical bonds and can be used immediately or converted to starch for long-term storage. Different plants store this energy-rich food in different places: leaves, roots, stems, fruits, or seeds. Choice C is correct because it identifies sugar as what plants make to store the captured light energy, and mentions that sugar can be turned into starch later for long-term storage. Choice A fails because water is used in photosynthesis but doesn't store energy—it's a raw material, not an energy storage molecule. Choice B fails because oxygen is a waste product of photosynthesis, not an energy storage compound. Choice D fails because chlorophyll captures light but doesn't store it—the energy is transferred to sugar molecules. To teach this: Show students a potato (stored starch) and explain it started as sugar made in leaves. Trace the path: sunlight → captured by chlorophyll → used to make sugar → sugar travels to potato → converted to starch for storage.
- Where do plants store energy after making sugar in the leaves?
Answer: in leaves, roots, stems, fruits, and seeds
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. After plants make sugar in their leaves during photosynthesis, they transport and store this energy-rich food throughout the plant. Different plants store energy in different parts: lettuce stores it in leaves, carrots store it in roots, potatoes store it in underground stems, apples store it in fruits, and corn stores it in seeds. The sugar (and starch made from sugar) can be stored wherever the plant needs energy for growth or wherever it saves energy for reproduction or surviving winter. Choice C is correct because it accurately identifies that plants store energy in leaves, roots, stems, fruits, and seeds. This demonstrates understanding that energy storage occurs throughout the plant in various organs, not just in one location. Choice A fails because it claims energy is stored in air pockets, when energy is stored in food molecules within plant tissues. Choice B fails because it states storage occurs only in roots, when many plant parts store energy. Choice D fails because it suggests chlorophyll holds energy forever, when chlorophyll captures light but energy is stored in sugar and starch molecules. To help students understand: Use familiar foods to show energy storage locations—'Where does a carrot store energy? (root) An apple? (fruit) Corn? (seed) Lettuce? (leaves) Potato? (underground stem).' Create a plant diagram labeling where different plants store their energy-rich food. Emphasize that the energy is IN the food molecules (sugar/starch), which can be stored in many different plant parts.
- The model shows energy stored in food; when animals eat plants, what do they get?
Answer: chemical energy stored in sugar and starch from sunlight
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. The model shows energy stored in plant food (sugar and starch), and the question asks what animals get when they eat plants. When animals eat plants, they consume the sugar and starch that contain chemical energy in their molecular bonds. Animals then break down these food molecules to release the stored energy for their own life processes. This demonstrates the energy transfer from sun to plant to animal. Choice A is correct because it accurately identifies that animals get chemical energy stored in sugar and starch that originally came from sunlight—this shows understanding of energy transformation and transfer through food chains. Choice B fails because light energy is not still shining inside leaves—it has been converted to chemical energy. Choice C fails because heat is not trapped in plants for storage—energy is stored as chemical bonds in food molecules. Choice D fails because plants don't store electrical energy—the stored form is chemical energy in food. Teaching strategy: Create a simple food chain diagram: Sun (light) → Plant (makes sugar/starch) → Rabbit (eats plant, gets chemical energy) → Fox (eats rabbit, gets chemical energy). Emphasize that the energy changes form but originated from the sun.
- How do plants store the energy they capture from sunlight during photosynthesis?
Answer: by making sugar and starch with stored chemical energy
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. When plants capture light energy from the sun during photosynthesis, they transform it into a different form of energy that can be stored. Plants use light energy to make sugar molecules, and the sugar stores the energy in its chemical bonds—this is called chemical energy. Some sugar is used right away, but much is stored for later use, either as sugar or as starch. Different plants store this energy-rich food in different places: leaves, roots, stems, fruits, and seeds. Choice C is correct because it accurately describes that plants store energy by making sugar and starch with stored chemical energy. This demonstrates understanding that energy is stored in food molecules and that the stored form is chemical energy, not light or heat. Choice A fails because it claims plants keep light energy shining inside leaves, when light energy is converted to chemical energy. Choice B fails because it states energy is held in water, when water is used in photosynthesis but doesn't store energy. Choice D fails because it suggests energy is stored in soil, when plants store energy in their own tissues as food. To help students understand energy storage: Use food examples—ask 'What gives you energy when you eat an apple?' (The sugar and other food molecules). Trace the energy: 'Energy in apple ← made by apple tree ← using sunlight.' Demonstrate the transformation with a diagram showing light energy being converted to chemical energy in sugar. Watch for students who think energy stays as light or is stored in water/soil rather than in food molecules.
- According to the explanation, how is sunlight energy stored as sugar or starch in plants?
Answer: as chemical energy in sugar and starch

Some sugar is used right away by the plant for growth, but much of it is stored for later use, either as sugar or as starch (starch is made from many sugar molecules connected together, and is good for long-term storage). Choice B is correct because it accurately describes that plants store energy as chemical energy in sugar and starch. This demonstrates understanding that energy is stored in a usable form (food molecules) in various parts of the plant, and that the stored form is chemical energy, not light or heat. Choice A fails because it claims energy is stored as heat, when the stored form is chemical energy in food molecules.

So the energy you get from eating a carrot originally came from the sun!'
- According to the explanation, which plant part can store energy as sugar in fruit?
Answer: apple fruit storing sugar made from sunlight
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. The question asks about energy storage in fruit, using an apple as an example. When apple trees photosynthesize, they make sugar in their leaves using sunlight energy. This sugar travels through the tree and accumulates in developing apples, where it's stored as sugar (making apples sweet) and can be partially converted to starch. The apple fruit serves as an energy storage organ for the tree. Choice A is correct because it accurately describes apple fruit storing sugar made from sunlight—the fruit is a storage location for chemical energy originally captured from the sun. Choice B fails because soil doesn't store the plant's energy—plants store energy in their own tissues as food molecules. Choice C fails because chlorophyll captures light energy but doesn't store it—the energy is transferred to sugar molecules for storage. Choice D fails because oxygen is a waste product of photosynthesis and air spaces are for gas exchange, not energy storage. To help students: Bring an apple to class and explain its sweetness comes from sugar that stores energy from sunlight—when you eat an apple, you're eating stored sunshine!
- How do plants store the energy they capture from sunlight during photosynthesis?
Answer: by turning it into sugar and starch stored in plant parts
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. When plants capture light energy from the sun, they don't store it as light—they transform it into a different form of energy that can be stored; during photosynthesis, plants use light energy to make sugar (a type of food), and the sugar molecules store the energy in their chemical bonds—this is called chemical energy, with some sugar used right away for growth and much stored as starch for later use in various plant parts like leaves, roots, stems, fruits, and seeds. Choice A is correct because it accurately describes that plants store energy by turning it into sugar and starch stored in plant parts, demonstrating understanding that energy is stored in a usable form (food molecules) in various parts of the plant, and that the stored form is chemical energy, not light or heat. Choice B fails because it claims energy is stored by keeping it as light inside leaves until night ends, when light energy is converted to chemical energy in food; energy must be stored in a stable form that can be used later—sugar and starch molecules store energy in chemical bonds, not as light. To help students understand energy storage in plants, use food examples they eat like potatoes (stores energy in underground stems), carrots (in roots), apples (in fruits), corn (in seeds), and lettuce (in leaves), and ask 'Where did the energy in this carrot come from?' while tracing backwards from the sun; demonstrate with an energy flow diagram showing Sun (light energy) → Plant captures light → Plant makes sugar → Sugar stores chemical energy → Stored in plant parts, emphasizing energy changes from light to chemical and is stored in food molecules, not in water, chlorophyll, light, or heat.
- The model shows plants store energy by moving sugar to which plant parts?
Answer: to leaves, roots, stems, fruits, and seeds
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. The model shows that after plants make sugar through photosynthesis, they transport it through their vascular system to various parts for storage: leaves store sugar for immediate use, roots store it as starch (like in carrots), stems can store it (like in potatoes), fruits store it to attract animals for seed dispersal, and seeds store it to fuel germination. Choice A is correct because it identifies all major plant parts where sugar can be transported and stored, demonstrating understanding of energy distribution throughout the plant. Choices B, C, and D fail because soil doesn't store plant energy; chlorophyll captures but doesn't store energy; and air pockets don't store light—only sugar and starch molecules in plant tissues store energy.
- The model shows leaves make sugar; how does that stored energy help later?
Answer: The plant or animals can use the stored food energy later
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. The beauty of storing energy as food (sugar and starch) is that it can be used later when needed. Plants use stored food energy for growth at night, for sprouting in spring, or for making flowers and fruits. Animals (including humans) that eat plants get this stored energy and use it for their own life activities. The chemical energy in food can be released when needed, unlike light which cannot be stored directly. Choice A is correct because it accurately describes that plants or animals can use the stored food energy later. This demonstrates understanding that chemical energy in food is accessible and usable when needed. Choice D fails because it claims plants cannot store energy and must use all sunlight immediately, when the whole point of photosynthesis is to convert light energy into storable chemical energy in food. Plants absolutely can and do store energy as sugar and starch for later use. To help students understand: Discuss examples—a potato sprouts using stored starch energy, a bear eats berries to get stored sugar energy, seeds germinate using their stored food. Create a 'before and after' diagram: 'Sunny day = making and storing food' → 'Night/winter = using stored food for energy.' Emphasize: Storing energy as food allows life to continue even when the sun isn't shining!

Choice C fails because it states energy is stored as light trapped in leaves, when light energy is converted to chemical energy in food. Choice D fails because it suggests electricity is stored in plant cells, which is not how plants store energy. To help students understand energy storage in plants: Use food examples they eat—potato (stores energy in underground stem), carrot (stores in root), apple (stores in fruit), corn (stores in seeds), lettuce (stores in leaves). Ask: 'Where did the energy in this carrot come from?' Trace backwards: 'Energy in carrot ← made by carrot plant ← using sunlight ← sunlight came from sun. So the energy you get from eating a carrot originally came from the sun!'
- Plants convert light energy from the sun into what stored form during photosynthesis?

This demonstrates understanding that energy is stored in a usable form (food molecules) in various parts of the plant, and that the stored form is chemical energy, not light or heat. Choice C fails because it states energy is stored as oxygen in the air, when oxygen is a byproduct of photosynthesis but doesn't store energy. Energy must be stored in a stable form that can be used later—sugar and starch molecules store energy in chemical bonds, not in water, chlorophyll, light, or heat. To help students understand energy storage in plants: Use food examples they eat—potato (stores energy in underground stem), carrot (stores in root), apple (stores in fruit), corn (stores in seeds), lettuce (stores in leaves). Emphasize two key points: (1) Energy changes form from light to chemical, and (2) Energy is stored IN the food (sugar/starch), not in water, chlorophyll, or other plant parts.
- How do plants store the energy they capture from sunlight during photosynthesis?
Answer: by turning light into sugar and starch for storage
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. During photosynthesis, plants capture light energy and use it to make sugar molecules from carbon dioxide and water. The key transformation is that light energy becomes chemical energy stored in the bonds of sugar and starch molecules—this stored chemical energy can be used later by the plant or by organisms that eat the plant. Choice A is correct because it accurately describes that plants turn light into sugar and starch for storage, showing understanding of the energy transformation from light to chemical energy in food molecules. Choice B fails because light energy cannot be kept shining or stored as light—it must be converted; Choices C and D fail because energy is stored as chemical energy in food molecules, not as heat or in water.
- Plants convert light energy from the sun into energy stored as what?
Answer: chemical energy in sugar, sometimes changed into starch
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. During photosynthesis, plants capture light energy from the sun and use it to make sugar molecules. The light energy doesn't stay as light—it's converted into chemical energy stored in the bonds of sugar molecules. Plants often convert some of this sugar into starch (many sugar molecules connected together) for more efficient long-term storage. The key transformation: light energy from the sun becomes chemical energy in sugar, which can be changed into starch. Choice A is correct because it accurately describes that plants convert light energy into chemical energy in sugar, sometimes changed into starch. This demonstrates understanding of the energy transformation from light to chemical form and that both sugar and starch are storage molecules. Choice B fails because it claims energy is stored as heat kept warm, when the stored form is chemical energy in food molecules. Choice C fails because it states light energy is saved like a flashlight, when light must be converted to chemical energy to be stored. Choice D fails because it suggests oxygen gas is stored as fuel, when oxygen is a byproduct and energy is stored in sugar/starch. To help students understand: Draw the energy conversion—Sun (light) → Leaf (captures light) → Sugar (chemical energy) → Starch (chemical energy for long-term storage). Ask: 'Why do we eat food for energy? Because food like sugar and starch contains chemical energy!' Emphasize the transformation: 'Plants are energy converters—they change light energy into chemical energy we can eat.'
- The explanation says sugar stores energy in its chemical bonds; this energy came from what?
Answer: sunlight captured by green leaves during photosynthesis
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. The question traces energy backwards from its stored form (sugar) to its original source. Sugar molecules store energy in their chemical bonds, and this energy originally came from sunlight that was captured by chlorophyll in green leaves during photosynthesis. The plant used the light energy to power the chemical reactions that built sugar molecules from simpler materials. Choice A is correct because it accurately identifies sunlight captured by green leaves during photosynthesis as the original source of energy stored in sugar's chemical bonds. Choice B fails because soil nutrients provide materials (like nitrogen and minerals) but not energy—energy comes from sunlight. Choice C fails because water is a raw material used to make sugar but doesn't provide the energy. Choice D fails because plant color (chlorophyll) captures energy but needs sunlight—it can't make energy without light. Teaching strategy: Draw an energy flow diagram: Sun → Light energy → Captured by chlorophyll → Powers sugar-making → Energy stored in sugar bonds. Ask students to trace where the energy in an apple originally came from, working backwards to the sun.
- According to the explanation, where is energy stored in an apple or tomato?
Answer: as sugar stored in the fruit that was made using sunlight
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. Fruits like apples and tomatoes are storage organs that plants use to hold energy-rich food. The plant's leaves capture sunlight and make sugar through photosynthesis. Some of this sugar is transported to developing fruits, where it accumulates. This is why fruits taste sweet—they're packed with sugar that stores chemical energy originally from sunlight. The energy is in the sugar molecules themselves, not in the color, heat, or water of the fruit. Choice A is correct because it accurately describes that energy is stored as sugar in the fruit that was made using sunlight. This demonstrates understanding that fruits store chemical energy in food molecules, specifically sugar. Choice B fails because it claims light is stored in the fruit's bright color, when color is just reflected light wavelengths—the actual energy is stored as chemical energy in sugar molecules. Energy must be converted from light to chemical form to be stored. To help students understand: Cut open an apple and taste its sweetness. Explain: 'This sweet taste is sugar—that's where the energy is stored!' Draw the path: Sunlight → apple tree leaves → leaves make sugar → sugar travels to growing apple → apple stores sugar → you eat apple and get energy. Emphasize: The energy is IN the sugar, not in the color or juice.
- According to the explanation, what form does sun energy take when stored in plants?
Answer: as chemical energy in sugar and starch made during photosynthesis
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food.

This demonstrates understanding that energy is stored in a usable form (food molecules) in the plant, and that the stored form is chemical energy, not light or heat. Choice B fails because it claims energy is stored as light, when light energy is converted to chemical energy in food. Energy must be stored in a stable form that can be used later—sugar and starch molecules store energy in chemical bonds, not as light, heat, or electricity. To help students understand energy storage in plants: Use food examples they eat—potato (stores energy in underground stem), carrot (stores in root), apple (stores in fruit). Ask: 'Where did the energy in this carrot come from?' Trace backwards: 'Energy in carrot ← made by carrot plant ← using sunlight ← sunlight came from sun. So the energy you get from eating a carrot originally came from the sun!'
- How do plants store sunlight energy so they can use it later?
Answer: by storing it as food sugar and starch
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. Plants capture sunlight energy during photosynthesis and transform it into sugar molecules, where the energy is stored in chemical bonds. This sugar (and starch made from sugar) serves as the plant's energy storage system—like a battery that can be used later when the plant needs energy for growth, reproduction, or survival during times without sunlight. Choice B is correct because it identifies that plants store sunlight energy as food (sugar and starch), demonstrating understanding that energy must be converted to a storable chemical form. Choices A, C, and D fail because light, water, and heat cannot be stored for later use—only the chemical bonds in food molecules provide a stable, accessible form of stored energy.

Demonstrate the transformation: draw an energy flow diagram with Sun (light energy) → Plant captures light → Plant makes sugar → Sugar stores energy as chemical energy → Stored in plant parts.
- According to the explanation, where can plants store sugar or starch after photosynthesis?
Answer: in leaves, roots, stems, fruits, and seeds
This question tests the ability to use models to explain how plants store energy from sunlight in food (NGSS 5-PS3-1). Students must understand that light energy is converted to chemical energy stored in plant food. After photosynthesis produces sugar in the leaves, plants transport this sugar throughout their body and can store it in various parts. Lettuce stores energy in leaves, carrots in roots, potatoes in underground stems, apples in fruits, and corn in seeds. The sugar may be kept as sugar or converted to starch for more efficient long-term storage. Choice C is correct because it accurately lists the various plant parts where sugar or starch can be stored: leaves, roots, stems, fruits, and seeds. Choice A fails because energy is not stored in the soil—plants absorb water and minerals from soil but store energy in their own tissues. Choice B fails because the green color (chlorophyll) captures light but doesn't store energy—the energy is stored in sugar and starch molecules. Choice D fails because air pockets don't store energy—they allow gas exchange but energy is stored in food molecules. To help students: Bring examples of each storage location—spinach leaf, carrot root, potato stem, apple fruit, corn seed—and explain each contains stored sunlight energy as sugar or starch.
