Plz solve Q no. 7 for 5 mark question
Dear Student
The chlorophyll pigments are present in the thylakoid membranes have the property of excitability and emits electrons in the excited stage, though this electron is replaced and transferred by the electron generated from splitting of water molecules.
Red and Blue light have maximum energy which a chlorophyll pigment absorbs and get excited and initiate the process of photosynthesis. Its wavelength is (400-700 nm) i.e., between the Photosynthetic Active Radiation (PAR). Thus, the rate of photosynthesis is higher in blue and red light.
Also, chlorophyll can only absorb certain wavelength of visible light spectrum. It absorbs only red and blue regions of the spectrum. Chlorophyll gets destroyed very easily by excess energy. For this reason they only absorb some amount of wavelengths specifically red and blue.

Chlorophyll cannot absorb green light. They normally reflect back the green light from the light spectrum. For this reason we can see the plant parts containing chlorophyll green. As they cannot absorb energy from green light they cannot perform photosynthesis also in green light.
