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

Front

What are the inputs of photosynthesis?

Back

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

Front

What are the outputs of photosynthesis?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is the second stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of the chloroplast.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the main energy carrier in cells, providing energy for various cellular processes, including the Calvin cycle in photosynthesis.

Front

What are grana in chloroplasts?

Back

Grana are stacks of thylakoids in chloroplasts where the light-dependent reactions of photosynthesis occur.
