Which light range is most effective in photo- synthesis

A

Blue

B

Green

C

Red

D

Violet

Text Solution

Verified by Experts

The correct Answer is:
c
As per the diagram given in 'Devlin's-: Plant Physi- ology· the graph shows maximum absorption by chloro- phyll a & b in the wavelength of blue region, followed by that in the red region. This hints very well to the quality of light that is most effective in the process of photosyn- thesis. But, some authors say that red light is more energy efficient in photosynthesis than blue ligh!. How- ever, a controversy exists and so the answer given by Exemplar can be accepted
