What is photosynthesis?
Click to flip
Photosynthesis is a process by which green plants, algae, and some bacteria convert light energy, carbon dioxide, and water into glucose and oxygen.
Click to flip
What are the two main stages of photosynthesis?
Click to flip
The two main stages are the Light-dependent reactions and the Calvin Cycle (Light-independent reactions).
Click to flip
Where in the cell does photosynthesis occur?
Click to flip
Photosynthesis occurs in the chloroplasts of plant cells.
Click to flip
What pigment is primarily involved in photosynthesis?
Click to flip
Chlorophyll is the primary pigment involved in photosynthesis.
Click to flip
What is the chemical equation for photosynthesis?
Click to flip
The chemical equation is 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.
Click to flip
What are the products of the light-dependent reactions?
Click to flip
The products are ATP, NADPH, and oxygen.
Click to flip
What role does water play in photosynthesis?
Click to flip
Water provides electrons and protons and releases oxygen as a byproduct.
Click to flip
What is photolysis?
Click to flip
Photolysis is the splitting of water molecules using light energy during photosynthesis.
Click to flip
What is the Calvin Cycle?
Click to flip
The Calvin Cycle is the set of light-independent reactions in photosynthesis that produce glucose.
Click to flip
How does carbon dioxide enter a plant?
Click to flip
Carbon dioxide enters through the stomata, small openings on the underside of a leaf.
Click to flip
What is the function of ATP in photosynthesis?
Click to flip
ATP provides the energy needed for the Calvin Cycle to synthesize glucose.
Click to flip
What is the function of NADPH in photosynthesis?
Click to flip
NADPH provides electrons and hydrogen ions for the Calvin Cycle.
Click to flip
How does light intensity affect photosynthesis?
Click to flip
Increasing light intensity boosts the rate of photosynthesis up to a point before leveling off.
Click to flip
How do temperature changes impact photosynthesis?
Click to flip
Temperature affects enzyme activity; optimal temperatures maximize photosynthesis, while extremes inhibit it.
Click to flip
What is chlorophyll's role in photosynthesis?
Click to flip
Chlorophyll absorbs light, providing energy for photosynthesis.
