Chlorophyll a Absorbs Which Wavelength S the Best

Photosystem II has a pair of chlorophyll molecules also known as P680 as the molecules best absorb light of the wavelength 680 nm. Each photosystem has a reaction centre consisting of chlorophyll a molecule and antennae containing accessory pigments.

Chlorophyll absorbs the red and blue segment of the white light and photosynthesis occurs most efficiently at these wavelengths.

. When the light falls on the plant the chlorophyll pigment absorbs this light and electrons in it gets excited. The P680 donates a pair of electrons after absorbing light energy resulting in an oxidized form of P680. Its important to note light spectrums affect plant growth differently depending on things like environmental conditions crop species etc.

This process occurs in a complex protein system which is collectively called as a photosystem. The reaction centre for PS-I is P-700 because the absorption peak for chlorophyll a is at 700 nm while that for PS-II is P-680 because the absorption peak for chlorophyll a is at 680 nm. Typically chlorophyll the molecule in plants responsible for converting light energy into chemical energy absorbs most light in blue and red light spectrums for photosynthesis.
