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 main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is: CO₂ + light + H₂O → O₂ + glucose.

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What happens during the light reactions of photosynthesis?

Back

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

Front

Where do the light reactions take place?

Back

The light reactions take place in the thylakoid membranes of the chloroplasts.

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

Where does the Calvin Cycle occur?

Back

The Calvin Cycle occurs in the stroma of the chloroplasts.

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.
