Question

Two potted plants were kept in an oxygen free environment in transparent containers Plant A was exposed to green light and plant B to sunlight. Which one of the two, is likely to survive longer and why?

Answer 1

Plant A will show more photosynthesis.Chlorophyll absorbs maximum light in the blue region of the spectrum, i.e., 400-450 nm and hence photosynthetic rate will also be high.

Plant B will show negligible amount of photosynthesis or no photosynthesis as chlorophyll does not absorb any light in the green region,i.e., 500-550 nm but reflects light.
