Its singular form is called stoma, and it means 'mouth'. Stomata function is to regulate the process of photosynthesis, transpiration, respiration, etc. In this article we are going to discuss this structure and function in plants, which is an important part of plant biology. Positioning and Structure.

Glucose is used as a food source, while oxygen and water vapor escape through open stomata into the surrounding environment.
