Light phase - needs light
Dark phase - does not need light
2 different reactions: 1. light dependent reaction (light reaction) - requires the use of light 2. light independent reaction (dark reaction/calvin-benson cycle) - does not require the use of light
The first phase of photosynthesis is the Light-Dependent Phase, the second phase is the Light-Independent Phase.
light-dependent and light-independent.
The products of the light reaction are 18 ATP, 12 NADPH2 and 6O2 (which is actually a byproduct.)
