Photosynthesis is a process by which organisms produce food substances from CO2 and water in presence of sun light
photosynthesis is the process of making food in the leaves of plants in presence of sunlight,water,carbondioxide and chlorophyll. food can be prepared in plants having green colour,that colouris due to the presence of chlorophyll given by the green pigment chloroplast.during the process of photosynthesis carbondioxide is used by the plants and oxygen is givenout
Photosynthesis is the process by which plants containing the green pigment 'chlorophyll' build up complex organic molecules like carbohydrates,proteins,lipids etc. from relatively simple inorganic ones,using sun light as an energy source.
That's my textbook definition.Hope it helped you :)
