Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy 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 Calvin cycle (light-independent reactions).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What are the inputs of the photosynthesis process?

Back

The inputs of photosynthesis are carbon dioxide (CO2), water (H2O), and light energy.

Front

What are the outputs of photosynthesis?

Back

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

Front

What happens during the light-dependent reactions?

Back

During the light-dependent reactions, light energy is converted into chemical energy in the form of ATP and NADPH, and oxygen is released as a byproduct.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that uses ATP and NADPH to convert carbon dioxide into glucose.

Front

What is a thylakoid?

Back

A thylakoid is a membrane-bound compartment inside chloroplasts that contains chlorophyll and is the site of the light-dependent reactions.

Front

What is stroma in the context of chloroplasts?

Back

Stroma is the fluid-filled space inside chloroplasts where the Calvin cycle takes place.
