What is photosynthesis?

Photosynthesis is a process by which green plants, algae, and some bacteria convert light energy, carbon dioxide, and water into glucose and oxygen.

What are the two main stages of photosynthesis?

The two main stages are the Light-dependent reactions and the Calvin Cycle (Light-independent reactions).

Where in the cell does photosynthesis occur?

Photosynthesis occurs in the chloroplasts of plant cells.

What pigment is primarily involved in photosynthesis?

Chlorophyll is the primary pigment involved in photosynthesis.

What is the chemical equation for photosynthesis?

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

What are the products of the light-dependent reactions?

The products are ATP, NADPH, and oxygen.

What role does water play in photosynthesis?

Water provides electrons and protons and releases oxygen as a byproduct.

What is photolysis?

Photolysis is the splitting of water molecules using light energy during photosynthesis.

What is the Calvin Cycle?

The Calvin Cycle is the set of light-independent reactions in photosynthesis that produce glucose.

How does carbon dioxide enter a plant?

Carbon dioxide enters through the stomata, small openings on the underside of a leaf.

What is the function of ATP in photosynthesis?

ATP provides the energy needed for the Calvin Cycle to synthesize glucose.

What is the function of NADPH in photosynthesis?

NADPH provides electrons and hydrogen ions for the Calvin Cycle.

How does light intensity affect photosynthesis?

Increasing light intensity boosts the rate of photosynthesis up to a point before leveling off.

How do temperature changes impact photosynthesis?

Temperature affects enzyme activity; optimal temperatures maximize photosynthesis, while extremes inhibit it.

What is chlorophyll's role in photosynthesis?

Chlorophyll absorbs light, providing energy for photosynthesis.
