Question:
Which property of the pigment is responsible for its ability to initiate the process of photosynthesis? Why is the rate of photosynthesis higher in the red and blue regions of the spectrum of light?
Solution:
The most abundant pigment in plants is chlorophyll a. This pigment demonstrates the optimal efficiency between blue and red-light wavelengths. Pigments are capable of
absorbing light with a certain wavelength so they absorb various colours of light. Pigments show optimal efficiency between the blue and red light. This is due to the
chlorophyll and also can be due to the accessory pigments. This means that in the range of red and blue light the rate of photosynthesis is higher.
