Answer» $photosystem(i)$ ✴️ It is constitute by those chlorophyll P(700) and other pigment molecules which absorb light energy and pass on to P(700). ✴️ The reaction centre is P(700). ✴️ The electrons emitted by this come BACK as de-energized electrons. ✴️ It is involved both in cyclic and non - cyclic photophosphorylation. $photosystem(ii)$ ✴️ It is constitute by those chlorophyll P (680) and accessory pigments that pass on light energy to P(680). ✴️ The reaction centre is P(680). ✴️ The electrons emitted by this do not come back but are replaced by electrons GENERATED by photolysis of water. ✴️ It is involved only in non-cyclic photophosphorylation.
