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?

If chlorophyll were red instead of green, making plants red in appearance, the red color of light would be expected to produce the lowest rate of photosynthesis.

Chlorophyll is a photosynthetic pigment in plants, which absorbs photon of light in order to use during photosynthesis (synthesis of glucose). If the chlorophyll of a plant is red, this means that it will absorb all other colors of light except red light. This means red light will yield the lowest rate of photosynthesis. Therefore, if chlorophyll were red instead of green, making plants red in appearance, the red color of light would be expected to produce the lowest rate of photosynthesis.

If chlorophyll were red instead of green, making plants red in appearance, red light would produce the lowest rate of photosynthesis.

Explanation:

As plants contain green pigments called chlorophyll so they appear green in color. It barely absorbs green light, the reflection of green makes it look 'green color'. So if the chlorophyll was red, it reflects all the red light meaning the there won’t be conversion of energy in the plant tissue through photosynthesis.
