What is the relationship between the rate of photosynthesis and the absorption of light by chlorophyll a pigment?
  1. The rate of photosynthesis is high when light is absorbed by chlorophyll a pigment in the blue and red regions.
  2. The rate of photosynthesis is high when light is absorbed by chlorophyll a pigment in the yellow region.
  3. The rate of photosynthesis is high when light is absorbed by chlorophyll a pigment in the yellow-orange region.
  4. The rate of photosynthesis is low when light is absorbed by chlorophyll a pigment in the blue and red regions.

Solution

The graph showing the ability of chlorophyll a pigment to absorb lights of different wavelengths shows that the wavelengths at which there is maximum absorption by chlorophyll a, i.e., in the blue and the red regions, also show a higher rate of photosynthesis.
