psi splits water to get electrons.
psi contains the pigment chlorophyll.
psi is needed to make nadph.
psi uses light energy to energize electrons.

Photosystem II (PSII), not PSI, splits water to get electrons. PSI contains chlorophyll pigment, is needed in the process to make NADPH (in non - cyclic photophosphorylation), and uses light energy to energize electrons.
