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, and releasing oxygen as a byproduct.

Front

What are the main components required for photosynthesis?

Back

The main components required for photosynthesis are sunlight, carbon dioxide, and water.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

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 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

What happens during the light-dependent reactions of photosynthesis?

Back

During the light-dependent reactions, sunlight is absorbed by chlorophyll, water is split to release oxygen, and energy carriers (ATP and NADPH) are produced.

Front

What occurs during the Calvin cycle?

Back

During the Calvin cycle, carbon dioxide is fixed into glucose using the energy from ATP and NADPH produced in the light-dependent reactions.

Front

What is the equation for photosynthesis?

Back

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

Front

How does photosynthesis benefit the ecosystem?

Back

Photosynthesis benefits the ecosystem by producing oxygen, which is essential for the survival of aerobic organisms, and by providing organic matter (glucose) that serves as food for various organisms.

Front

What is the significance of the oxygen produced during photosynthesis?

Back

The oxygen produced during photosynthesis is crucial for the survival of most living organisms, as it is used in cellular respiration.
