Photosynthesis

Front

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

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of chloroplasts.

Front

What is the primary pigment involved in photosynthesis?

Back

The primary pigment involved in photosynthesis is chlorophyll.

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP and NADPH are produced, along with oxygen as a byproduct.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is used in the Calvin cycle to produce glucose.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (C6H12O6).

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is released as a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

How do plants obtain water for photosynthesis?

Back

Plants obtain water through their roots from the soil.

Front

What is the function of ATP in photosynthesis?

Back

ATP provides the energy needed for the light-independent reactions (Calvin cycle) to synthesize glucose.
