Photosynthesis is an enzymatic controlled anabolic process in which there is a synthesis of organic compounds inside the chlorophyll containing cells from the water and CO2 in the presence of sunlight.
OR
Photosynthesis is a process in which green plants makes their own food in the presence of sunlight from the H2O and CO2 with the help of chlorophyll molecules.
OR
Photosynthesis is a process in which there is a conversion of light energy into chemical energy.
6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O
The function of water is to provide hydrogen for the synthesis of organic compounds and liberation of oxygen during the process.
The organisms which has the ability to perform photosynthesis are called photoautotrophs. All green plants, cyanobacteria, algae and many protists are photoautotrophs.
Importance
i) Photosynthesis is the only process in which synthesis of organic molecules from the inorganic raw material is possible.
ii) Photosynthesis plays very important role in releasing oxygen into atmosphere to compensate for O2 using through the process of respiration. It helps in maintaing the balance between O2 and CO2 level in the atmosphere.
iii) All heterotrophs are depends on photoautotrophs for their food requirements.
iv) All types of fossil fuels like coal, petroleum and natural gas are the results of photosynthesis.
v) Many plant products are very useful like timber for making furniture, doors and windows, rubber, resins, drugs, oils, fibres etc.
vi) Crops productivity is directly dependent upon the rate of photosynthesis.
