Is a pore on the under layer of a leaf, used for gas exchange in plants.
In botany, a stoma (plural stomata), also called a stomate (plural stomates) (from Greek στόμα, mouth), is a pore, found in the epidermis of leaves, stems, and other organs, that is used to control gas exchange. 1. a minute opening in leaves, stems, etc., through which gases are exchanged. 2. a primitive mouth or simple ingestive organ of an invertebrate animal. 3. a surgical opening in an organ constructed to permit passage of fluids or waste products to another organ or to the outside of the body. stoma stóma]. mouth′sto, mal. adj 1. a minute opening in leaves, stems, etc., through which gases are exchanged. 2. a primitive mouth or simple ingestive organ of an invertebrate animal. 3. a surgical opening in an organ constructed to permit passage of fluids or waste products to another organ or to the outside of the body. stoma stóma]. mouth′sto, mal. adj Photosynthesis is the process by which plants convert sunlight into usable energy. During photosynthesis, carbon dioxide is taken in from the atmosphere through the stomata and oxygen is released as a waste product. Both photosynthesis and the gas exchange that powers it are essential to the plant's survival. Structure. A stoma is the opening on a plant leaf, but there are specialized cells surrounding each stoma that control how open or closed it is. These specialized cells are called guard cells, and they are triggered by a number of factors, such as sunlight, humidity, temperature, and internal plant chemistry. 1. stomate-a minute epidermal pore in a leaf or stem through which gases and water vapor can pass. stoma, pore. aperture-a natural opening in something. germ pore-a pore in the outer wall of a spore or pollen grain through which the germ tube or pollen tube makes its exit on germination. A stomate (plural: stomata) is a pore on the under layer of a leaf, used for gas exchange in plants. One guard cell is located on either side of the stomate, and these are res … ponsible for the opening and closing of the hole. Carbon dioxide is taken into the plant to be used in photosynthesis, while oxygen (product of photosynthesis) and water vapor (through transpiration) escape from the stomata.
