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

Front

What are chloroplasts?

Back

Chloroplasts are organelles found in plant cells and some algae that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the stroma?

Back

The stroma is the fluid-filled interior space of the chloroplast where the Calvin cycle 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 the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH.

Front

What is the significance of light reactions in photosynthesis?

Back

Light reactions capture solar energy and convert it into chemical energy in the form of ATP and NADPH, which are then used in the Calvin cycle.

Front

What is NADPH?

Back

NADPH is a short-term energy carrier that provides the reducing power needed for the Calvin cycle in photosynthesis.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells and is produced during the light reactions of photosynthesis.
