Light is needed to excite electrons in the electron transport chain to commence photosynthesis.
That is the dark reaction. It needs no light
Chlorophyll is NOT really a catalyst. The presence of chlorophyll in the absence of light does not catalyze photosynthesis. Chlorophyll plays a part in photosynthesis, it captures light energy.
Chlorophyll is the pigment in plant cells that absorbs light energy for photosynthesis.
The light phase. THE Calvin cycle....
The light-dependent reactions in photosynthesis generate oxygen from water. No ATP is produced during this step.

Chloroplasts are the part of a cell responsible for photosynthesis. They contain chlorophyll, which is the pigment that absorbs light energy used in photosynthesis to convert carbon dioxide and water into glucose and oxygen.
Yes, all plants do; it's a required part of photosynthesis.
It is the chloroplast.It is responsible for photosynthesis.
A.T.P. and N.A.D.H are formed during light reaction.
No, PS I and PS II are part of the first stage of photosynthesis, the light reactions. The Calvin cycle is the second stage of photosynthesis and does utilize the photosystems.
Traps light energy for use in photosynthesis.
