Which of the following options best explains how less chlorophyll would affect the proces of
photosynthesis in plants?
6.
A. It would increase the rate of photosynthesis because of the increased production of food.
B. It would limit the amount water plants are able to take in, resulting in a slower rate of
photosynthesis.
C. It would increase the production of oxygen because the plant would need to work hard to
feed themselves.
С.
D. It would limit the amount of light absorbed by the plant and decrease the amount of food
the plant is able to produce for itself.
