What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is produced during the light-dependent reactions of photosynthesis?

Back

Oxygen is produced during the light-dependent reactions of photosynthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What is the light-independent stage of photosynthesis also known as?

Back

The light-independent stage of photosynthesis is also known as the Calvin Cycle.

Front

What do plants need from the environment to perform photosynthesis?

Back

Plants need sunlight, carbon dioxide, and water from their environment to perform photosynthesis.

Front

What is ATP and why is it important in photosynthesis?

Back

ATP (adenosine triphosphate) is an energy-carrying molecule produced during the light-dependent reactions, and it provides the energy needed for the light-independent reactions.

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to convert solar energy into chemical energy in the form of ATP and NADPH, while releasing oxygen as a byproduct.

Front

Do animal cells have chloroplasts?

Back

No, animal cells do not have chloroplasts; they lack the ability to perform photosynthesis.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is essential for the production of glucose during the light-independent reactions (Calvin Cycle) of photosynthesis.
