What is the role of chlorophyll in photosynthesis?

• It reflects all colors of light

• It captures carbon dioxide from the air

• It converts water into oxygen directly

• It absorbs red and blue light, reflecting green

Where do the light-dependent reactions of photosynthesis occur?

• In the stroma

• In the nucleus

• In the mitochondria

• In the thylakoids

What are the products of the light-dependent reactions?

• ADP and NADP+

• Glucose and oxygen

• ATP and NADPH

• Carbon dioxide and water

What is the Calvin Cycle also known as?

• The dark reaction

• The pigment cycle

• The light reaction

• The chlorophyll process

What is required for the Calvin Cycle to occur?

• Carbon dioxide only

• Chlorophyll only

• ATP and NADPH from the light-dependent reactions

• Light only

What is the purpose of stomata in plants?

• To absorb water

• To intake carbon dioxide

• To release oxygen

• To capture light

What is the main difference between photosynthesis and cellular respiration?

• Cellular respiration produces light

• Cellular respiration occurs only in animals

• Photosynthesis does not require oxygen

• Photosynthesis produces glucose, while cellular respiration breaks it down
