Explanation:
(a) The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. photosynthesis in plants generally the green pigment chlorophyll and generates oxygen as a product.
b) CO2 +H2O SUNLIGHT/ CHLOROPHYLL --- C6+H2O6 + O2
Photosynthesis :
Green plants make their food by a biochemical process with the help of carbon dioxide and water in the presence of sunlight and chlorophyll . This process is known as photosynthesis .
Chemical equation :
6CO² + 12 H²O----> C6H12O6 +6H²O +6O²
Mechanism of photosynthesis :
Chlorophyll is present in chloroplast. Leaves contain chlorophyll A and B. Photosynthesis occurs in two phases: (a) photochemical or light dependent phase and
(b) biosynthetic or light independent phase .
During light reaction light energy is trapped by chlorophyll , water is split into H+ and OH- ions and ATP from ADP and NADPH from NADP are formed. During the reaction NADPH and ATP molecules are utilised to produce sugar (glucose ) . The end product of photosynthesis are glucose , water and oxygen .
In simple words , solar energy (light energy from the sun ) is converted into chemical energy to be stored in the food molecules. Since plants use energy from sunlight for the synthesis of food . Simple sugars from carbon dioxide and water by the cells of green plants in presence of chlorophyll and using solar energy are produced . Oxygen gas is given out as a by - product
