it is something to do with electrons and being charged!
Excited Electrons
Light excites two sets of photosynthetic pigments. These are photosystem 1 (PS1) and photosystem 2 (PS2). PS1 is excited by photons at about 700 nanometers, while PS2 is excited at about 680 nanometers.
The cells do with all those high-energy electrons in carriers like NADH? in the presence of oxygen, those electrons can be used to generated huge amounts of ATP.

the energy absorbed or released by atoms
The electrons emit photons of light equal in energy to the energy that was absorbed.
The electrons emit photons of light equal in energy to the energy that was absorbed.
It allows the energy of absorbed light to be trapped and converted to chemical energy.
Light energy is absorbed by chlorophyll and other pigments in chloroplasts
The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.
