A) chloroplasts within wilted leaves are incapable of photosynthesis.
B) CO₂ accumulates in the leaves and inhibits the enzymes needed for photosynthesis.
C) there is insufficient water for photolysis during the light reactions.
D) stomata close, restricting CO₂ entry into the leaf.
E) wilted leaves cannot absorb the red and blue wavelengths of light.
