Photosynthesis (UPDATED)

What are the primary products of photosynthesis?

• Carbon dioxide and water

• Glucose and oxygen

• ATP and NADPH

• Light and heat

How do the overall chemical equations for photosynthesis and cellular respiration relate to each other?

• They are identical processes.

• The reactants of photosynthesis are the products of cellular respiration, and vice versa.

• Both processes only produce ATP.

• Photosynthesis produces glucose, while cellular respiration produces oxygen.

Where do the light-dependent reactions of photosynthesis take place within a plant cell?

• Stroma

• Cytoplasm

• Thylakoids

• Mitochondria

Cacti living in hot, dry environments have an adaptation called CAM photosynthesis. How does this adaptation help them survive?

• They absorb more sunlight during the day.

• They open their stomata at night to collect carbon dioxide and close them during the day to conserve water.

• They have larger leaves to capture more water.

• They perform photosynthesis only at night.
