• Sun

• Reactants

• Photosynthesis

What is "Photosynthesis"?

• A chemical reaction where animals produce glucose.

• A chemical reaction where plants produce glucose.

• A chemical reaction where plants break down glucose.

• A chemical reaction where animals break down glucose.

What is the process by which plants convert light energy into chemical energy?

• Respiration

• Photosynthesis

• Transpiration

• Decomposition

What is the main product of photosynthesis?

• Oxygen

• Carbon dioxide

• Water

• Glucose

What is needed in order for photosynthesis to take place?

• Sun and water only.

• Sun, water, and carbon dioxide.

• Sun, water, and oxygen.

• Sun, water, and oxygen.

How do plants absorb water?

• Water enters the plants at the leaves.

• Water enters the plants at the stems.

• Water enters the plants through the air.

• Water enters the plants at the roots.

This is the gas that plants take in.

• carbon dioxide

• oxygen

• glucose

• water

Plants get energy from
