The cell plasma.
Many chemical reactions occur in water solutions. But a reaction can be realized also in solid or gaseous phase.

Heat
Light usually provides enough energy for exchange of electrons and carry out the chemical reaction.
Carbohydrates
Because vital chemical reactions take place in water, and water is necessary to sustain life because of the important elements it has and the refreshment and nourishment it provides to organisms.
Major is the carbohydrates.Lipids is also a good sourse
Starch
An easily understood explanation is: NADPH carries high-energy electrons that were produced by light absorption in chlorophyll to chemical reactions elsewhere in the cell. NADPH is a chemical compound which gives hydrogen atom for the formation of the carbohydrate in the dark reactions of the photosynthesis. Photosynthesis is completed in two steps: Light reactions dark reactions Another explanation: NADPH provides a source of hydrogen for reduction reactions in photosynthesis. In the light independent reactions carbon dioxide is converted into carbohydrate: CO2 --------> CH2O NADPH provides the hydrogen needed for this reaction.
