Found in the thylakoid membranes of chloroplasts, photosystems are clusters of chlorophyll and other pigment molecules that absorb sunlight for photosynthesis.
A photosystem is a mechanism in plants that absorbs light energy for them. This is a crucial part of the photosynthesis process of the plant.
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
Photosystem 1 and Photosystem 2
No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.
Both photosystem 2 & 1 are light-dependent.
Photosystem 1
1. Photosystem I is found in the membrane facing the inside of the grana and Photosystem II is found in membrane facing the stromaTHYLAKOID MEMBRANE
NADPH

Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.

Photosystem 1 and Photosystem 2
the cluster of pigment molecules is a photosystem.
No, they move from photosystem 2 to photosystem 1. 2 evolved first but was not discovered until after photosystem 1.
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
Both photosystem 2 & 1 are light-dependent.
Photosystem II most likely evolved first because it provides the energy for producing ATP and passes its electrons to photosystem I.
