There is a light reaction and a dark reaction (the Calvin Cycle). The light reaction is divided into 3 parts, Photosystem II, the Electron Transport Chain, and Photosystem I. The light reaction begins in Photosystem II when light hits the thylakoid so the chlorophyll loses and electron, and the electron moves up in energy levels and reaches the primary anceptor. From here it passes through the electron transport chain which is similar to the electron transport chain in cellular respiration, but it occurs in the thykaloids proton gradient is reversed through the membrane. Then it enters phtosystem I which is essentially the same thing as photosystem I, and the electrons from there pass through another electron transport chain. This produces ATP and NADPH which are used in the dark reaction, or Calvin Cycle, which is again similar to the Citric Acid Cycle but it begins with Acetyl acetate and produces 2 ATP 6 NADH and 1 FADH 2 per every 2 turns which are required to produce one glucose molecule, the ultimate goal of photosynthesis.
I hope this was enough detail.
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
I would take it as what happen after photosynthesise. Give out oxygen and make food. I not sure I am correct. But do view other relevant answers, there are 3 , some would say.
light-dependent and light-independent.
Light reaction always need light.It takes place only at day time. Dark reaction does not need lighti think it's DARK REACTION PHASE and LIGHT REACTION PHASE...:]
[it's just a guess but I'm 100% sure of it... :))]
The light dependent reactions and the light independent reactions.

ATP and NADPH fuel the dark reactions of photosynthesis.
There are two steps. Light dependent and light independant reactions

Photosynthesis consists of two stages: a series of light-dependent reactions that are temperature independent and a series of temperature-dependent reactions that are light independent. The rate of the first series, called the light reaction, can be increased by increasing light intensity (within certain limits) but not by increasing temperature. In the second series, called the dark reaction, the rate can be increased by increasing temperature (within certain limits) but not by increasing light intensity.
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
Photosynthesis is the process that plants convert solar energy into the energy stored in chemical bonds. This consists of two reactions, light dependent and light independent.
Light Reactions and the Calvin Cycle Reactions.
There are two reactions. Those are light dependent and independent.
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.

There are three carbon dioxide, water, and sunlight.
