Stomata are the small pores present in the epidermal cells of leaf and stem.Stomata are mainly responsible for vital processes like photosynthesis, respiration, transpiration etc. The primary stomata function is to take in carbon dioxide and release oxygen, this is done with the assistance of guard cells which voluntarily open and close the pore for the exchange of gases; the process involving gas and water exchange is called transpiration. Transpiration rates increase, when stomata are open, and it decreases when it is closed. Stomata: Some minute pores which are usually, found in leaf for the exchange of gas and transpiration are known as stomata (singular stoma). Once this happens, pressure is developed that forces the roots to absorb water from the soil and transfer it to the tips of the plant. ...
