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 is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

What do plants produce during photosynthesis?

Back

Plants produce carbohydrates (such as glucose) and oxygen during photosynthesis.

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 are chlorophyll and its role in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What are the products of the light-dependent reactions?

Back

The products of the light-dependent reactions are ATP and NADPH.

Front

What is the Calvin cycle?

Back

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

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light-dependent reactions to release oxygen.

Front

What is the significance of oxygen produced in photosynthesis?

Back

Oxygen produced in photosynthesis is released into the atmosphere and is essential for the respiration of most living organisms.
