Question

Which statement is or are correct according to above figure:

• A. A-show the action spectrum of chlorophyll a
• B. B-shows the absorption spectrum of chlorophyll a
• C. On study of A and B together, it shown that in blue and red region higher rate of photosyntesisthat mean chl-a is chief pigment.
• D. (2) & (3) both

Answer 1

The correct option is A A-show the action spectrum of chlorophyll a

A-shows the action spectrum of chlorophyll a that means it shows maximum photosynthesis occurs in blue-violet and red parts of the light

B-Shows the absorption spectrum of chlorophyll a that means Chlorophyll a absorb maximum light in the blue-violet and red parts of the light.

Action spectrum of photosynthesis corresponds closely to absorption spectra of chlorophyll a showing that the chl-a is the main photosynthetic pigment.

So, the correct answer is 'A-show the action spectrum of chlorophyll a'.
