Photosynthesis is a biochemical

Photosynthesis is a biochemical process in which plants, algae, and some bacteria used to produce energy (nutrients) using light energy. Nearly all living things depend on energy produced from photosynthesis. As a result of photosynthesis is very important for life on earth. Photosynthesis is also credited with producing most of the oxygen present in Earth's atmosphere.
Organisms that produce energy through photosynthesis (photos meaning light) is called fototrof. Photosynthesis is one way for the photosynthetic carbon assimilation of CO2 free carbon bound (fixed) to gulasebagai energy storage molecules. Another way to be taken is the organism to assimilate carbon through chemosynthesis, by some sulfur bacteria.
Until now photosynthesis was studied further because there are still a number of steps that can not be explained, even though it very much is known about this vital process. The process of photosynthesis is very complex because it involves all the main branches of the natural sciences, such as physics, chemistry or biology alone.
In plants, the main organ of photosynthesis is the site of the leaf. But in general, all the cells that have the potential to establish a chloroplast reaction. At the site of the photosynthetic organelle is, exactly in the stroma. Of photosynthesis (called photosynthate) is usually sent to a nearby tissues first. Basically, a series of reactions of photosynthesis can be divided into two main parts: the light reaction (because it requires light) and dark reactions (do not require light but require carbon dioxide).
