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 function of chlorophyll in photosynthesis?

Back

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

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 equation for photosynthesis?

Back

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

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

What is produced during the light-dependent reactions of photosynthesis?

Back

The light-dependent reactions produce oxygen, ATP, and NADPH.

Front

What role does water play in photosynthesis?

Back

Water is split during the light-dependent reactions to provide electrons, protons, 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 significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, and is essential for the respiration of most living organisms.
