How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which option correctly shows water movement into and through a plant in a model?

Answer: Soil $\rightarrow$ roots $\rightarrow$ xylem $\rightarrow$ leaves. Water travels upward through specialized transport tissue.

Flashcard 2: What is the role of sunlight in a matter-tracing model of photosynthesis: matter source or energy source?

Answer: Energy source (not a source of matter). Light powers the process but doesn't become part of the sugar.

Flashcard 3: In a model, which substance is a reactant (input) for photosynthesis inside leaves?

Answer: Carbon dioxide ($CO_2$). Gas enters through stomata to provide carbon for sugar synthesis.

Flashcard 4: In a model, which substance is a reactant (input) for photosynthesis that comes from the soil?

Answer: Water ($H_2O$). Absorbed by roots and transported to leaves for photosynthesis.

Flashcard 5: In a matter-tracing model, which arrow correctly shows carbon movement into a plant?

Answer: $CO_2$ in air $\rightarrow$ leaf $\rightarrow$ sugar in plant. Carbon enters through stomata and becomes part of sugar molecules.

Flashcard 6: Which option correctly traces sugar movement after it is made in leaves?

Answer: Leaves $\rightarrow$ phloem $\rightarrow$ stems, roots, fruits. Sugar flows through living tubes to all growing parts.

Flashcard 7: Identify the correct label for the leaf process: $CO_2$ in + light in $\rightarrow$ sugar + $O_2$ out.

Answer: Photosynthesis. This equation summarizes the inputs and outputs of the process.

Flashcard 8: Which statement best matches a matter model: plant mass increases mainly because of matter from where?

Answer: From $CO_2$ in the air (not mainly from soil). Most plant mass comes from carbon fixed from air, not soil nutrients.

Flashcard 9: Which product of photosynthesis is a sugar that stores matter and chemical energy for the plant?

Answer: Glucose ($C_6H_{12}O_6$). This 6-carbon sugar is the main energy storage molecule.

Flashcard 10: Which gas is released to the environment as a product of photosynthesis?

Answer: Oxygen ($O_2$). Released from water molecules split during light reactions.

Flashcard 11: Which cell structure contains chlorophyll and is the main site of photosynthesis in plants?

Answer: Chloroplast. Green organelles capture light energy for sugar synthesis.

Flashcard 12: What is the main source of the carbon atoms that end up in a plant’s sugar molecules?

Answer: Carbon dioxide ($CO_2$) from the air. Plants get carbon from air, not soil, to build sugars.

Flashcard 13: What is the main source of the hydrogen atoms that end up in a plant’s sugar molecules?

Answer: Water ($H_2O$) absorbed from the soil. Roots absorb water, which provides hydrogen for sugar synthesis.

Flashcard 14: What is the main source of the oxygen atoms that end up in a plant’s sugar molecules?

Answer: $CO_2$ from air and $H_2O$ from soil. Oxygen in glucose comes from both reactants in photosynthesis.

Flashcard 15: Which plant structure absorbs water and dissolved minerals from the soil into the plant?

Answer: Roots (especially root hairs). Root hairs increase surface area for water and mineral absorption.

Flashcard 16: Which plant tissue transports water upward from roots to leaves?

Answer: Xylem. Hollow tubes carry water up against gravity through the plant.

Flashcard 17: Which plant tissue transports sugars made in leaves to other parts of the plant?

Answer: Phloem. Living cells transport food from where it's made to where it's needed.

Flashcard 18: Which tiny openings in leaves allow $CO_2$ to enter and $O_2$ and water vapor to exit?

Answer: Stomata. Guard cells control these pores for gas exchange.

Flashcard 19: What is the name of the process in which plants use light to make sugar from $CO_2$ and $H_2O$?

Answer: Photosynthesis. Light energy converts inorganic molecules into organic sugar.

Flashcard 20: Identify the correct path in a model for sugar leaving a leaf: leaf to stem to which tube type?

Answer: Phloem. Sugar moves through phloem to feed all plant parts.

Flashcard 21: Identify the correct path in a model for water moving into a leaf: soil to root to which tube type?

Answer: Xylem. Water travels upward through xylem vessels to leaves.

Flashcard 22: Which statement correctly traces a carbon atom: from air $CO_2$ to which plant molecule first?

Answer: Into sugar (glucose) made in photosynthesis. Carbon atoms from $CO_2$ become part of glucose structure.

Flashcard 23: Identify the correct place in a model where most of a plant’s mass comes from: soil minerals or air $CO_2$?

Answer: Air $CO_2$. Most plant mass comes from carbon in air, not soil.

Flashcard 24: Which statement best matches a matter-tracing model: sunlight enters as matter or as energy?

Answer: Sunlight enters as energy, not matter. Light provides energy to drive reactions, not physical matter.

Flashcard 25: Which environmental material is taken in by plants to supply minerals for growth?

Answer: Minerals (nutrients) dissolved in soil water. Provides nitrogen, phosphorus, and other elements for growth.

Flashcard 26: Which substance is a product of photosynthesis that is released from leaves into the air?

Answer: Oxygen gas ($O_2$). Byproduct released when water splits during photosynthesis.

Flashcard 27: What is the name of the tubes that model sugar movement from leaves to the rest of the plant?

Answer: Phloem. Transports sugars throughout the plant from leaves.

Flashcard 28: What is the name of the tubes that model water movement from roots to leaves?

Answer: Xylem. Transports water and minerals upward from roots.

Flashcard 29: Which plant structure is modeled as the main entry point for water from the environment?

Answer: Roots (especially root hairs). Root hairs increase surface area for water absorption.

Flashcard 30: Which plant structure is modeled as the main entry point for $CO_2$ from the air?

Answer: Stomata in the leaves. Tiny pores that open to let gases in and out of leaves.
