Overall Equation of Photosynthesis Heterotrophic Nutrition The overall equation of photosynthesis is:įig.2. The stomata/stoma is surrounded by a guard cell which guards the opening and closing of stomata. Leaves contain small openings known as stomata which helps in the exchange of gases. Finally, reduction of carbon dioxide into carbohydrates.Splitting of water into hydrogen and oxygen.Conversion of light energy into chemical energy.The steps of photosynthesis are as follows. They contain a green colour pigment known as chlorophyll that traps sunlight for photosynthesis. The site where photosynthesis occurs is known as chloroplast. Water is taken up from the soil through the roots. Sunlight provides energy, chlorophyll is used to absorb the sunlight, carbon dioxide is reduced to carbohydrates and water is oxidised to release the oxygen. Now the question arises how does autotrophic nutrition occur in plants using photosynthesis?įor photosynthesis to occur, carbon dioxide, water, sunlight and chlorophyll are the required raw materials. Organisms that use the autotrophic mode of nutrition are known as autotrophs. For example, green plants use an autotrophic mode of nutrition. It is a type of nutrition in which inorganic materials such as carbon dioxide, is used up to synthesise organic food by a process known as photosynthesis. The two most common types of nutrition are autotrophic nutrition and heterotrophic nutrition. that are necessary for the survival of the living organisms are known as life processes.
