Detailed explanation-1: -PSI is sensitive to longer wavelength of light.
Detailed explanation-2: -The main factors, which are responsible for the light sensitivity of photosystem II, are excited pigment molecules, oxygen, manganese, as well as electron donors with high-oxidizing potential.
Detailed explanation-3: -In photosystem l, the reaction centre has an absorption peak at 700 nm (red light), hence is called P700 and in PS ll, the reaction centre has an absorption peak at 680 nm (red light), hence is called P680.
Detailed explanation-4: -Photosystem 1 (PS1) absorbs light of wavelength 700nm, while photosystem 2 (PS2) absorbs light of wavelength 680nm. The photosystems are present in the chloroplast.
Detailed explanation-5: -1 Answer. Photosynthesis is most efficient at wavelengths 400 to 500 nanometers ( nm ) and between 600 to 700 nm.
