Photosynthesis Quiz

What is the primary function of chloroplasts in plants?

• Transpiration

• Photosynthesis

• Digestion

• Respiration

Which pigment is primarily responsible for absorbing light in chloroplasts?

• Chlorophyll

• Anthocyanins

• Carotenoids

• Xanthophylls

What are the products of the light reaction in photosynthesis?

• Carbon dioxide and water

• RuBP and G3P

• ATP and NADPH

• Glucose and oxygen

In which part of the chloroplast does the Calvin cycle occur?

• Thylakoid membrane

• Stroma

• Granum

• Outer membrane

What is the main role of Rubisco in photosynthesis?

• To release oxygen

• To absorb light

• To fix carbon dioxide

• To produce ATP

Which type of plants utilize the C4 pathway for photosynthesis?

• Tropical plants

• Desert plants

• Temperate plants

• Aquatic plants

What is photorespiration?

• The synthesis of glucose from carbon dioxide

• The conversion of light energy to chemical energy

• A wasteful process that occurs when O2 binds to Rubisco

• A process that enhances photosynthesis

What is the overall equation for photosynthesis?

• 6O2 + 6H2O → 6CO2 + C6H12O6

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 6CO2 + 6H2O → C6H12O6 + 6O2

• C6H12O6 + 6CO2 → 6H2O + 6O2

What is the primary factor that limits the rate of photosynthesis under certain conditions?

• Carbon dioxide concentration

• Light intensity

• Water availability

• Temperature

Which of the following is a characteristic of C3 plants?

• Adapted to hot climates

• Photosynthesis occurs in bundle sheath cells

• Low CO2 saturation requirement

• High water use efficiency
