Give a brief description of the process of synthesis of food in green plants.

Autotrophs (Make their own food) take in CO2 (Carbon Dioxide) and H20 (Water) which is converted to carbohydrates in the presence of sunlight and chlorophyll.Carbohydrates provide energy to the plants.Carbohydrates of no immediate use is stored as starch. Photosynthesis have 3 steps as follows-- (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of H2O(Water) into Hydrogen and Oxygen. (iii) Reduction of CO2(Carbon Dioxide) to carbohydrates

green plants prepare their own food from simple raw material available from the soil and the atmosphere. The process of preparation of food by the plants is called photosynthesis. Photosynthesis is the process by which chlorophyll present in the leaves/green parts of the plant converts inorganic raw materials as carbon dioxide and water to glucose and oxygen in the presence of light energy (sunlight). Most photosynthesis takes places in the green parts of plants, in particular the leaves. The process of photosynthesis involves 2 stages. These are 1) Light-dependent Stage and 2) the Light-independent stage. In the light-dependent stage, water is photolyzed by sunlight into Hydrogen and oxygen. Of these, hydrogen enter the second stage, while oxygen is released as by-product. In the light - independent stage enzymes catalyze the reduction of carbon dioxide by hydrogen to produce glucose. This glucose may either be used immediately by the plant or trans located in the form of fructose, sucrose or stored as starch granules.
