Here is ur answer

Question => why photosystem 2 takes place before photosystem 1?

Answer => Photosystem II works with Photosystem I and two series of enzymes imbedded in the thylakoid membrane to transfer energy from the form of light to that stored in chemical bands and gradients which the plant can use in a process called noncyclic photophosphorylation.
