Stoma vs. Lenticel

Stomanoun

(botany) One of the tiny pores in the epidermis of a leaf or stem through which gases and water vapor pass.

Stomanoun

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.

Stomanoun

(zoology) A mouthlike opening, such as the oral cavity of a nematode.

Stomanoun

An artificial anus.

Stomanoun

One of the minute apertures between the cells in many serous membranes.

Stomanoun

The minute breathing pores of leaves or other organs opening into the intercellular spaces, and usually bordered by two contractile cells.

Stomanoun

A stigma. See Stigma, n., 6 (a) & (b).

Stomanoun

a minute epidermal pore in a leaf or stem through which gases and water vapor can pass

Stomanoun

a mouth or mouthlike opening (especially one created by surgery on the surface of the body to create an opening to an internal organ)

Stomanoun

any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases in and out of the intercellular spaces.

Stomanoun

a small opening like a mouth in some lower animals.

Stomanoun

an artificial opening made into a hollow organ, especially one on the surface of the body leading to the gut or trachea.

Stoma

In botany, a stoma (from Greek στόμα, , plural ), also called a stomate (plural ) is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.

Lenticelnoun

One of the small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue, either in the air, or more commonly when the stem or branch is covered with water or earth.

Lenticelnoun

A small, lens-shaped gland on the underside of some leaves.

Lenticelnoun

One of the small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue, either in the air, or more commonly when the stem or branch is covered with water or earth.

Lenticelnoun

one of many raised pores on the stems of woody plants that allow the interchange of gas between the atmosphere and the interior tissue

Lenticel

A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases.
