Stoma
small opening in leaves that allow gases in and out
Stoma refers to an opening or a small hole in the surface of a plant or animal. It is primarily used for transportation and exchange purposes, as it facilitates the movement of gases and water in and out of the organism. In plants, stomata are present on the leaves and stems, and they play an important role in the process of photosynthesis by regulating the exchange of carbon dioxide and water vapor through the process of transpiration. In animals, stomata are found in the digestive system, respiratory system, and excretory system, and they allow for the absorption of nutrients and the removal of waste products from the body. Overall, stomata are important structures that contribute to the survival and functioning of both plants and animals.
