Read the following statements and choose the follwoing option: 1. Most of the photosynthesis takes place in the green and yellow regions of the spectrum 2. Chlorophyll a is the chief pigment of photosynthesis 3. Accessory pigments cannot absorb light 4. Water stress causes the stomata to remain open hence increasing the CO2 availability.

Options

  1. AOnly 2 is correct
  2. BAll are correct
  3. COnly 3 is correct
  4. DBoth 2 and 4 is correct

Correct answer

A. Only 2 is correct

Step-by-step solution

The wavelengths at which there is maximum absorption by chlorophyll a, i.e., in the blue and the red regions, also shows higher rate of photosynthesis. Hence, we can conclude that chlorophyll a is the chief pigment associated with photosynthesis.
