Nutrition In Plants
The carbon and energy requirements of the autotrophic organisms are fulfilled by photosynthesis. It is a process by which autotrophs take in substances from the outside and convert them into the stored form of energy. This material is taken in the form of carbon dioxide and water, which is converted into carbohydrates in the presence of Sunlight and chlorophyll. Carbohydrates are utilised to provide energy to the plants. The carbohydrates that are not used immediately are stored in the form of starch, which serves as an internal energy reserve, to be used as and when required by the plant. A somewhat similar situation is seen in the US, where some of the energy derived from the food we eat is stored in our body in the form of glycerine. The steps that take place during photosynthesis are
Absorption of light energy by chlorophyll.
Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
Reduction of carbon dioxide to carbohydrates.
After all these steps are completed, the oxygen that is a waste material is released through the stomata pores and the extra water as well, and the exchange of gases also takes place.
