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 is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy, mainly in the blue and red wavelengths.

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 role of sunlight in photosynthesis?

Back

Sunlight provides the energy required to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the survival of aerobic organisms.

Front

What are the products of the light-dependent reactions?

Back

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

Front

What is the Calvin cycle?

Back

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

Front

What is the role of water in photosynthesis?

Back

Water provides electrons and protons for the light-dependent reactions and is split to release oxygen.
