Question

what color of light is least effective in driving photosynthesis? explain your answer.

Explanation:

Photosynthesis is driven by pigments like chlorophyll. Chlorophyll absorbs light in the red and blue regions of the spectrum. Green light is reflected by plants (which is why they appear green), indicating it is not absorbed effectively for photosynthesis.

Answer:

Green light is least effective in driving photosynthesis. Chlorophyll (the main pigment in photosynthesis) reflects green light rather than absorbing it for the photosynthetic process.
