Photosynthesis

Photosynthesis is a chemical reaction which happens in autotroph organisms, such as plants, and some protists. It only happens in organisms which have plastid (chloroplast) in their cell so that they can produce food by themselves (autotroph). It happens in leaf, in mesophyll (in palisade/spongy parenchyma tissue). The reaction is: 

6CO2+12H2O->C6H12O6+6O2+6H2O

To do photosynthesis autotroph organisms takes energy from light, especially sunlight. So usually photosynthesis happens in daytime. Some factors that effects photosynthesis:

1. Area of leaf
2. Number of chlorophyll
3. Number of stomata
4. Temperature
5. Wind
6. Water
7. Etc
