Question

What color of visible light does not chlorophyll absorb at all? What happens to that color of light?

a) Blue; reflected
b) Green; absorbed for photosynthesis
c) Red; transmitted
d) Yellow; converted into heat

Answer 1

Chlorophyll does not absorb green light; it reflects it, which is why plants appear green. Green is not used for photosynthesis, transmitted, or converted into heat.

Step-by-step explanation:

The color of visible light that chlorophyll does not absorb at all is green. When light hits a chlorophyll-containing plant, the pigments absorb wavelengths from either end of the visible spectrum, specifically blue and red light, but they do not absorb green light. Instead, the green light is reflected back to our eyes, which is why plants appear green to us. Therefore, the correct answer to the question is that green light is reflected, not absorbed for photosynthesis, transmitted, or converted into heat.
