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 (a sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

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 does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the function of the stroma in chloroplasts?

Back

The stroma is the fluid-filled interior of the chloroplast where the Calvin cycle (light-independent reactions) takes place.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

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 light-independent reactions of photosynthesis.

Front

What is NADPH and its function in photosynthesis?

Back

NADPH is a carrier molecule that transfers high-energy electrons and is used in the Calvin cycle to help convert carbon dioxide into glucose.

Front

What is the significance of the Calvin cycle?

Back

The Calvin cycle is significant because it uses ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
