stoma teriminin İngilizce İngilizce sözlükte anlamı
A small opening in a membrane; a surgically constructed opening, especially one in the abdominal wall that permits the passage of waste after a colostomy or ileostomy
or stomate Any of the microscopic openings or pores in the epidermis of leaves and young stems. They are generally more numerous on the undersides of leaves. They provide for the exchange of gases between the outside air and the interconnecting air canals within the leaf. A stoma opens and closes in response to turgor pressure within its two surrounding guard cells. Because the inner wall of each of these sausage-or bean-shaped cells is thicker than the outer wall, when they fill with water and become turgid they balloon outward, enlarging the stoma. A drop in carbon-dioxide levels to lower than normal also causes the guard cells to become turgid. Guard cells control excessive water loss from the plant, closing on hot, dry, or windy days and opening when conditions are more favorable
A microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant
A surgically created opening into the gastrointestinal (bowel) or urinary system This is a general term and is sometimes used interchangeably with the word ostomy The stoma is red, moist, and is not painful
A microscopic pore or opening in the surface of a leaf that allows gases to pass in and out
a mouth or mouthlike opening (especially one created by surgery on the surface of the body to create an opening to an internal organ)
a microscopic opening in the surface of a leaf that allows gases to pass in and out
(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
a mouth or mouthlike opening (especially one created by surgery on the surface of the body to create an opening to an internal organ) a minute epidermal pore in a leaf or stem through which gases and water vapor can pass
A microscopically small opening in the epidermis of the green parts of a tree or other plant through which gasses pass out of and into the plant from the atmosphere
Located in the epidermis of plants stoma allow gas exchange between the plant and the environment
Artificial openings between two cavities or canals In this case, it is the passage from the upper pouch and the rest of the stomach Often casually used in converstation to also mean the upper pouch
Pore in the epidermis of plants through which gas exchange takes places; especially abundant on leaves
An artificial opening between an organ and the skin's surface, formed by surgery There are different types including a tracheostomy (formed from the windpipe), ileostomy (formed from the small bowel) colostomy (formed from the large bowel), and urostomy (formed from the bladder)
are tiny pores on the underside of leaves which allow air to enter and exit the plant It is through these stomata that plants take in carbon dioxide and let out oxygen into the air
Stomate: Small openings, usually found in the undersurface of a leaf which permit air exchange, and the escape of water vapour from the interior of the leaf Stomates are opened and closed through the action of guard cells
Openings in the epidermis of a stem or leaf of a plant which permit gas exchange with the air In general, all plants except liverworts have stomata in their sporophyte stage
Minute openings on the surfaces of leaves and stems through which gases (e g , oxygen, carbon dioxide, water vapor) and some dissolved materials pass into and out of plants
Small pores in plant leaves through which water vapor and carbon dioxide diffuse during transpiration and photosynthesis (carbon fixation), respectively
