It is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.
What do you mean by Chlorophyll?Chlorophyll may be defined as the green-colored pigment in plants, algae, and cyanobacteria that is essential for photosynthesis.
Chlorophyll A absorbs the light of wavelength 400 to 450nm with maximum intensity and 650 to 700nm with minimum intensity.
Chlorophyll B absorbs the light of wavelength 450 to 500nm with maximum intensity and 600 to 650nm with minimum intensity.
Therefore, it is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.
