n. (NL. fr. Gr. mouth - more at stomach) one of the minute openings in the epidermis of leaves, stems, and other plant organs through which gaseous interchange between the atmosphere and the intercellular spaces within these structures occur; the opening together with its associated guard cells and accessory cells. pl. stomata.
An artificial opening, such as a tracheostomy or colostomy
a surgically formed opening on a body surface
an artificial opening of the intestine to outside the abdominal wall.
an aperture in the epidermis, plural stomata.
A new body opening created during surgery.
A small, mouth-like, opening on the abdomen, made by surgery to bring a tube (such as an intestine) to the surface of the body. A stoma may be a temporary or permanent new route for bodily waste to leave the body.
( Stomata). The transpiring orifices in the epidermis of plants.
A surgically created opening from an area inside the body to the outside. Colostomy and urostomy are types of stomas. Also called an ostomy.
Tiny pore in the leaves and stems of plants. Gaseous diffusion (of carbon dioxide, oxygen, and water vapor) can occur through the pore.
a microscopic opening in the surface of a leaf that allows gases to pass in and out.
(plural: stomata) [Gr. stoma: mouth, opening] • Small opening in the plant epidermis that permits gas exchange; bounded by a pair of guard cells whose osmotic status regulates the size of the opening.
The leaves and stem of a plant are the site for photosynthesis, the process by which a plant makes its own food. In order to get hold of enough carbon dioxide for this process - and in order to get rid of the toxic build-up of oxygen, a waste product of photosynthesis, the plant needs to find a way of letting gasses into and out of leaves. It does so through the stomata, small pores in the leaves and stem which can be opened and closed by the swelling and contracting of two cells (the guard cells). In species adapted to a desert life, these may be sunk into deep pits on the stem and leaves to prevent water loss during gas exchange.
a surgically constructed opening, especially one made in the abdominal wall to permit the passage of waste. The stoma is usually on the abdominal wall in a hidden position, but occasionally can be down in the urethra.
(pl. stomata) Specialised pore in the epidermis (usually of leaves and stems) that allow gaseous exchange for photosynthesis and respiration and the transpiration of water vapour to the atmosphere.
( stomata pl.) - opening usual6 in the lower leaf epidermis that connect to intercellular space where gas exchange occurs between the spongy tissue and the outside air.
A temporary opening in the abdominal wall that allows the end of the small or large intestine to be brought through the abdomen and fastened onto the surface of the skin. This enables waste materials from the intestines to pass through the stoma and empty into a bag called a colostomy bag. This flexible bag is fastened to the skin around the stoma and fits close to the body.

Artificial opening between a body cavity or canal (such as the colon) and the skin.
An opening. In urology, stoma usually refers to the opening in the abdomen used for the drainage of urine.
An opening onto the outside of the body. There are several different types of stoma. A colostomy is an opening of the large bowel onto the outside of the abdomen. An ileostomy is an opening of the small bowel. A urostomy is an opening of the urinary system (made after the bladder has been removed).
Abbreviation for tracheostoma. This is the opening made at the front of the neck through which the tracheostomy tube is placed.

Stomata are pores (or openings) in plants' leaves. A stoma can open and close, controlling the loss of water from the plant.
A stoma (the plural is stomata) is a pore (or opening) in a plant's leaves. Most of the stoma are on the underside of the leaf. Guard cells open and close the stoma using turgor pressure, controlling the loss of water vapor and other gases from the plant.
In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the under-surface (epidermis) of a plant leaf, and used for gas exchange. The pore is formed by a pair of specialized parenchyma cells known as guard cells which are responsible for regulating the size of the opening. Air containing carbon dioxide enters the plant through these openings where it gets used in photosynthesis and respiration.
In medicine, a stoma (Greek - plr. stomata) is an opening, usually unnatural or surgically created, which connects a portion of the body cavity to the outside environment. Surgical procedures in which stomata are created are ended in the suffix '-ostomy' and begun with a prefix denoting the organ or area being operated on.
