What 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?

Answers (1)

Answer -

pigments present in plants help in absorbing light at a specific wavelength. This indicates that different plant pigments can be absorbed by different lights of the spectrum. After getting excited, a pigment provides light energy which can be utilised to initiate the process of photosynthesis.

The plants' cells are enriched in a green coloured pigment called chlorophyll. Chlorophyll indicates an optimum efficiency range between the red and blue wavelength ranges.
Chlorophyll-a is mainly responsible for keeping the photosynthesis at an optimum level of blue and red -light wavelengths.
