Photosynthesis Test

Front

What is the principal chemical compound that living things use to store energy?

Back

ATP (Adenosine Triphosphate) is the principal chemical compound used by living organisms to store and transfer energy.

Front

What happens to the O2 created in the light phase of photosynthesis?

Back

The O2 produced during the light phase diffuses out through the stoma of the leaves.

Front

What is the primary purpose of photosynthesis?

Back

The primary purpose of photosynthesis is to create glucose (carbohydrates) from carbon dioxide and water using sunlight.

Front

Which organelle in plant cells transforms light into glucose?

Back

Chloroplasts are the organelles in plant cells that convert light energy into chemical energy in the form of glucose.

Front

How does changing water levels affect photosynthesis?

Back

The graph of photosynthesis in relation to water levels typically starts low, increases to a peak, and then levels off.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin Cycle (light-independent reactions).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

How does light intensity affect the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis typically increases until it reaches a saturation point.
