Explain how chlorophyll contributes to the process of photosynthesis.

• It absorbs light energy and converts it into chemical energy.

• It transports water from roots to leaves.

• It releases oxygen as a byproduct.

• It stores glucose produced during photosynthesis.

Which factor does NOT directly affect the rate of photosynthesis?

• Light intensity

• Temperature

• Oxygen concentration

• Carbon dioxide concentration

Predict how a decrease in temperature might affect the rate of photosynthesis.

• The rate will increase due to faster enzyme activity.

• The rate will decrease due to slower enzyme activity.

• The rate will remain unchanged.

• The rate will increase due to more light absorption.
