Actually photosynthesis is a process in which green plants prepare their own food in the presence of oxygen,chlorophyll and sunlight. both the gases CO2 and O2 are important for the synthesis of food in plants. green plants releaseĀ O2 and absorb CO2 in order to prepare their food. thus it maintain a balance between both the gases by continuous release and absorbation.
