Photosynthesis Quiz

What is the primary purpose of photosynthesis?

• To produce oxygen for humans

• To convert sunlight into usable energy

• To absorb carbon dioxide

• To create ATP directly

Which part of the chloroplast is responsible for the light-dependent reactions?

• Stroma

• Grana

• Chlorophyll

• Thylakoid membrane

What is another name for the light-independent reactions?

• Chemiosmosis

• Electron transport chain

• Photorespiration

• Calvin Cycle

During the light-dependent reactions, what is the role of ATP and NADPH?

• To release oxygen

• To absorb sunlight

• To split water molecules

• To store and transfer energy

What happens to the electrons during the electron transport chain?

• They are absorbed by chlorophyll

• They are excited and move down the chain

• They are released as oxygen

• They are converted into glucose

What is the main product of the Calvin Cycle?

• Oxygen

• NADPH

• ATP

• Glucose

Which factor does NOT affect the rate of photosynthesis?

• Temperature

• Carbon dioxide concentration

• Light intensity

• Soil type

What is the CAM pathway primarily used for?

• Increasing photosynthesis rate

• Maximizing sunlight absorption

• Reducing water loss

• Enhancing oxygen production

Why do root cells lack chloroplasts?

• They are not exposed to sunlight

• They do not need to produce glucose

• They are part of the plant's support structure

• They are involved in water absorption

Which plants use the C4 pathway?

• Moss

• Cacti

• Pineapples

• Corn
