Example Question #1 : Support How Plants Need Air And Water To Grow

When humans or animals need energy, they find some food to eat. Plants do not get food in the same way. Plants must take materials from the environment and use energy from sunlight to make glucose, an energy-rich sugar. Plants use water and air to make food. Plants absorb water from the soil and take it in through their roots. The water travels up the stem and reaches the cells in the leave. Plants must have water to allow the nutrients to be absorbed. Plants allow carbon dioxide from the air to enter their leaves through tiny holes, and it enters the leaf cells. Without air, plants would be missing one of the ingredients necessary to create glucose.

Plants take light energy from sunlight to make their food. Light energy is not a material; it is an energy. Leaf cells trap light energy and use it to convert water and carbon dioxide into sugar. The sugar is stored as chemical energy in the plant. When this process takes place, leaf cells release oxygen as a byproduct. This process is called photosynthesis.

Which piece of text evidence supports why plants need air to grow?

Possible Answers:

Plants must have water to allow the nutrients to be absorbed.

Plants must take materials from the environment and use energy from sunlight to make glucose, an energy-rich sugar.

When this process takes place, leaf cells release oxygen as a byproduct.

Without air, plants would be missing one of the ingredients necessary to create glucose.

Correct answer:

Without air, plants would be missing one of the ingredients necessary to create glucose.

Explanation:

Air is necessary for plants to grow and survive. Plants take in carbon dioxide from the air and convert it into glucose through the process of photosynthesis, which is powered by sunlight. The piece of text evidence that supports this claim is, "Without air, plants would be missing one of the ingredients necessary to create glucose.". This piece of evidence is clear, based on scientific facts and processes, and is reasonable. It also provides the necessary support for the claim.

Explanation:

Water is necessary for plants to live and grow. The passage makes a claim, and it is supported by information and text evidence. One piece of text evidence that supports water's importance in a plant's survival is, "Plants must have water to allow the nutrients to be absorbed.". This piece of evidence is clear, based on scientific facts and processes, and is reasonable. It supports the claim and helps readers understand how important water is in the plant's life cycle.

Example Question #3 : Support How Plants Need Air And Water To Grow

Plants and trees can grow in a wide variety of environments. Whether they grow in the desert or the rainforest, they all have one thing in common, air and water are necessary for life and growth. Depending on the plant’s adaptations, the amount of water needed to survive varies. Some plants, like those in the desert, need very little water to grow. Plants primarily get the materials for growth from the air and water. Sunlight provides the energy that is required to create food through photosynthesis. We often see plants in soil, but it isn’t necessary for growth.

Hydroponics is a system of growing plants without soil. Nutrients are added to water and delivered directly through a plant’s roots. Plants do not gain anything from the earth itself; they absorb nutrients from within the soil. If those nutrients are added to the water, and the plant is in the open air, then the soil is not needed. Plants take in carbon dioxide from the air and convert it into glucose through the process of photosynthesis, which is powered by sunlight. Hydroponics come in numerous forms: the plants can be hung vertically, and the roots are sprayed, or roots may be submerged in water through a series of tubs, containers, or even coconut husks!

How does this passage support the claim that air and water are vital to a plant's growth?

Possible Answers:

This passage does not support the claim that air and water are vital to a plant's growth or survival.

This passage presents a case study about plants with and without water and air for readers to examine and draw conclusions from.

This passage provides specific data, facts, and experimental evidence to support the claim that water and air are vital to a plant's growth.

This passage provides information about how the plant uses air and water and why those materials are vital to the processes for growth.

Correct answer:

This passage provides information about how the plant uses air and water and why those materials are vital to the processes for growth.

Explanation:

Anyone can claim a scientific fact, but it is not valid unless there is evidence or information to support the claim. This passage provides information about how the plant uses air and water and why those materials are vital to the processes for growth. The text gives an example of hydroponics to disprove the misconception that plants must have soil to survive and thoroughly explains what the plants need air adn water for and how the materials are processed to aid in the growth and survival process.

Example Question #4 : Support How Plants Need Air And Water To Grow

Which structures of a plant are used in the absorption of water and carbon dioxide from the air?

Possible Answers:

Petals and stems

Leaves and flowers

Flowers and stems

Roots and leaves

Correct answer:

Roots and leaves

Explanation:

The leaves and roots of a plant are vital in the collection of water and carbon dioxide. Plants must take materials from the environment and use energy from sunlight to make glucose, an energy-rich sugar. Plants use water and air to make food. Plants absorb water from the soil and take it in through their roots. The water travels up the stem and reaches the cells in the leave. Plants must have water to allow the nutrients to be absorbed. Plants allow carbon dioxide from the air to enter their leaves through tiny holes, and it enters the leaf cells. Without air, plants would be missing one of the ingredients necessary to create glucose.

Example Question #5 : Support How Plants Need Air And Water To Grow

In 1642 most people thought that soil was the food for plants. Dr. Von Helmont from Belgium experimented on this topic for many years. He planted a 5-pound tree in a bucket with 200 pounds of soil. He watered the tree every day but did not add any more dirt. Von Helmont weighed the bucket after five years of allowing it to grow. The plant weighed 5 pounds, and the soil was 200 pounds at the beginning of the experiment. At the end of the research, in 1647, the plant weighed 169 pounds, and the soil was 199 pounds.

Based on Dr. Von Helmont's research, is soil the source of food for plants? Why or why not?

Possible Answers:

Soil may be the primary source of food for the plant, but Dr. Von Helmont did not complete the experiment correctly. He should have weighed the plant more than two times.

Yes, the soil is the plant's source of food. The plant consumed one pound of food over five years. This supports that the plants need to eat dirt.

There is not enough information in this passage to determine if the plant's primary source of food is soil or if something else provides its nutrients.

No, the soil is not the plant's source of food. There was only one pound of dirt missing at the end of the experiment. More soil would be missing if it were the primary source of food.

Correct answer:

No, the soil is not the plant's source of food. There was only one pound of dirt missing at the end of the experiment. More soil would be missing if it were the primary source of food.

Explanation:

Based on Dr. Von Helmont's research soil is not the main source of food for a plant. The weight of soil was only reduced by one pound in five years which alludes to the fact that something else may be providing the food with nutrients. In reality, plants are not eating or using the soil as food, they use materials from the air and water as well as sunlight to make their own food. Plants take in carbon dioxide from the air and convert it into glucose through the process of photosynthesis, which is powered by sunlight. Water supports the transportation of nutrients, from the soil up into the structures of the plant, is used in the process of photosynthesis, helps keep plants standing stiff and upright and not wilted or droopy, and water helps keep plants cool as it evaporates from the leaves.

Example Question #21 : Life Science

The saguaro cactus has adapted in numerous ways to protect the water that it collects during rare rainstorms in the desert. It has a vast root system that allows the plant to absorb water near the surface during rainfall. It also has thorns that deter thirsty animals from getting inside the stem of the cactus and drinking its water. The saguaro cactus also has a very thick, barrel-shaped stem used for holding water. Plants that are adapted to these dry places like the saguaro cactus, are called xerophytes. They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.

Which excerpt from the text supports the idea that the saguaro cactus needs water to survive?

Possible Answers:

It has a vast root system that allows the plant to absorb water near the surface during rainfall.

They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.

The saguaro cactus also has a very thick, barrel-shaped stem used for holding water.

It also has thorns that deter thirsty animals from getting inside the stem of the cactus and drinking its water.

Correct answer:

They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.

Explanation:

This passage described the adaptations of the saguaro cactus. The cactus lives in desert environments, which have very little rainfall. The piece of text evidence from the selection that best supports the idea that the saguaro cactus needs water to survive is, "They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.". This excerpt states that to grow and flourish, the cactus must collect, store, and conserve large amounts of water. This means that water is a vital resource for the plant, and it must have it to survive.

Example Question #22 : Life Science

The saguaro cactus has adapted in numerous ways to protect the water that it collects during rare rainstorms in the desert. It has a vast root system that allows the plant to absorb water near the surface during rainfall. It also has thorns that deter thirsty animals from getting inside the stem of the cactus and drinking its water. The saguaro cactus also has a very thick, barrel-shaped stem used for holding water. Plants that are adapted to these dry places like the saguaro cactus, are called xerophytes. They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.

Which claim below does this passage support?

Possible Answers:

Some plants need water. The cactus has adapted to like without water and only requires a tiny amount.

Water is an important resource for plants that live in desert environments. Plants in areas of rainfall do not depend on water.

All plants, even cacti, need water to survive and will adapt new ways to find and keep it.

None of these claims are supported by the passage.

Correct answer:

All plants, even cacti, need water to survive and will adapt new ways to find and keep it.

Explanation:

The claim that is supported by the passage is "All plants, even cacti, need water to survive and will adapt new ways to find and keep it.". The saguaro cactus has a vast root system, a thick stem, and thorns. These adaptations allow the cactus to survive in an environment of very little water which is an essential resource for all plants. The cactus has methods of retrieving water, storing it, and protecting it.

Example Question #23 : Life Science

True or False: Plants need air, light, carbon dioxide, and water to grow.

Possible Answers:

True

False

Correct answer:

True

Explanation:

The statement "Plants need air, light, carbon dioxide, and water to grow." is true. Plants need light from the sun to complete photosynthesis and water to stay hydrated and use in creating their food. They need oxygen for respiration, and they absorb carbon dioxide from the air for the transformation into oxygen, sugar, and carbohydrates. All of these things are necessary for their survival.

Example Question #24 : Life Science

Plants need ______________ from the air to complete the process of photosynthesis. They use this substance to create sugar and carbohydrates for nutrition and oxygen for cell respiration.

Possible Answers:

helium

potassium

moisture

carbon dioxide

Correct answer:

carbon dioxide

Explanation:

Plants need water, air, sunlight, and carbon dioxide to survive. Plants take in carbon dioxide from the air around them, and through the process of photosynthesis, they use the COand sunlight to make food for themselves. They cannot eat in the same manner as humans and animals, so carbon dioxide is an essential part of their survival process.

Example Question #25 : Life Science

A group of students had two identical trays of soil, each with ten tomato seedlings planted in them. Tray A was placed in direct sunlight. Tray B was placed in the dark. Both trays were given the same amount of water. After four weeks, the students observed both trays. Which tray of seedlings will have the most growth?

Possible Answers:

Neither tray will have any growth because they did not add fertilizer, which plants need.

Tray A will have had more growth because plants need sunlight to grow.

Both of the trays will have the same growth because they both received equal amounts of water.

Tray B will have had more growth because plants grow best in dark environments.

Correct answer:

Tray A will have had more growth because plants need sunlight to grow.

Explanation:

In this scenario, the plants with the most growth would be the plants in tray A. The plants in tray A received not only water (which plants must have to survive) but also sunlight. Plants need sunlight for the process of photosynthesis. If plants do not have access to air and sunlight, they cannot make their food and survive. The plants in tray B were deprived of sunlight, so they will not have as much growth as tray A.
