STOMATES Meaning and
Definition
-
Stomates, also known as stomata (singular: stoma), are specialized microscopic pores found on the surfaces of leaves, stems, and other plant organs. These tiny structures play a crucial role in the process of gas exchange in plants. The main function of stomates is to regulate the entry and exit of gases, such as carbon dioxide and oxygen, as well as water vapor, in and out of the plant.
Each stoma consists of two specialized cells known as guard cells, which surround the pore. These guard cells have the ability to open and close the stoma, allowing gas exchange to occur based on the needs of the plant. When the plant needs to take in carbon dioxide for photosynthesis or release oxygen, the guard cells swell and open up the stoma. Conversely, when the plant needs to conserve water, the guard cells shrink, causing the stoma to close.
By controlling the opening and closing of stomates, plants are able to balance the intake of carbon dioxide for photosynthesis with the release of oxygen and water vapor, while minimizing water loss through evaporation. This allows plants to maintain optimal levels of photosynthesis, which is vital for their growth and survival.
Additionally, stomates also play a role in the regulation of transpiration. Transpiration is the process of water loss from the plant through evaporation from the stomates. As the stomates open and close, they control the rate of transpiration, helping to regulate the plant's water balance and prevent excessive water loss.

Etymology of STOMATES
The word "stomates" is derived from the Greek word "stoma", meaning "mouth". In botany, stomates (also spelled stomata) refer to the tiny openings or pores found primarily on the surface of plant leaves, stems, and other plant organs. These openings allow for gas exchange, such as the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. The term "stomates" or "stomata" was first coined in the mid-19th century by German botanist Philipp Wilhelm Wirtgen.
