What is the primary sugar produced by plants during photosynthesis?

• Fructose

• Sucrose

• Glucose

• Lactose

Which of the following is a key difference between photosynthesis and cellular respiration?

• Photosynthesis produces oxygen, while cellular respiration consumes it

• Photosynthesis occurs in animals, while cellular respiration occurs in plants

• Photosynthesis produces ATP, while cellular respiration produces glucose

• Photosynthesis requires darkness, while cellular respiration requires light

Where do the light-dependent reactions of photosynthesis primarily occur within the chloroplast?

• Stroma

• Cytoplasm

• Thylakoids

• Mitochondria

What are the main products of the light-dependent reactions that are then used in the light-independent reactions (Calvin Cycle)?

• Carbon dioxide and water

• Glucose and oxygen

• ATP and NADPH

• Chlorophyll and light

How do plants performing CAM photosynthesis adapt to hot, dry environments?

• They absorb light only at night

• They open their stomata during the day to release excess water

• They store carbon dioxide at night and use it during the day

• They do not require water for photosynthesis
