Question

question 23
if chlorophyll were red instead of green, making plants red in appearance, which color of light would you expect to produce the lowest rate of photosynthesis?
blue light
white light
red light
green light

Explanation:

The color of an object is determined by the light it reflects. If chlorophyll were red, it would reflect red light and absorb other colors. Light that is reflected cannot be used for photosynthesis. So the color of light that is reflected (red light in this case) would produce the lowest rate of photosynthesis.

Answer:

C. Red light
