turgor

tur·gor

T0418900 (tûr′gər, -gôr′)n. The normal fullness or tension produced by the fluid content of living cells or of blood vessels and capillaries: leaves that have lost turgor.

[Late Latin, from Latin turgēre, to be swollen.]

turgor

(ˈtɜːɡə) n (Botany) the normal rigid state of a cell, caused by pressure of the cell contents against the cell wall or membrane. See also turgor pressure[C19: from Late Latin: a swelling, from Latin turgēre to swell]

tur•gor

(ˈtɜr gər)

n. 1. the normal distention or rigidity of plant cells, resulting from the pressure exerted by the cell contents on the cell walls. 2. the state of being swollen or distended. [1875–80; < Late Latin, = Latin turg(ēre) to swell + -or -or¹]

turgor

The internal tension that keeps a non-woody plant upright, created by the pressure of water in its tissues.

Turgor

turgor

[′tər·gər] (botany) Distension of a plant cell wall and membrane by the fluid contents.

Turgor

the state of tension of cell membranes that is caused by the osmotic pressure of the intracellular fluid (P int), the osmotic pressure of the external solution (P ext), and the resilience of the cell membrane. In animal cells, except for the cells of some Coelenterata, this resilience is generally minimal. Most animal cells lack turgor and maintain their integrity only in isotonic or near-isotonic solutions; in these cells the difference between the P int and the P ext is less than 0.5–1.0 atm.

In living plant cells, the P int is always greater than the P ext, but the cell membrane does not rupture owing to the presence of a cellulose cell wall. The difference between the P int and the P ext in such plants as halophytes and fungi reaches 50–100 atm, but even then the cell wall’s reserve of strength amounts to 60–70 percent. In most plants the relative elongation of the cell membrane that results from turgor does not exceed 5–10 percent, and the turgor pressure is in the range of 5–10 atm. Turgor gives plant tissues resilience and strength. All stages of autolysis, fading, and aging are accompanied by a decline in turgor.

V. V. KABANOV

turgor

[ter´ger] 1. swelling or other distention.2. a condition of normal tension in a cell or group of cells; fullness. adj., adj tur´gid.skin turgor a reflection of the skin's elasticity, measured by monitoring the time it takes for the skin of the forearm to return to position after it is lightly pinched between the examiner's thumb and forefinger. Normal turgor is a return to normal contour within three seconds; if the skin remains elevated (tented) more than three seconds, turgor is decreased.

Assessing skin turgor. From Lammon et al., 1995.

(tŭr'gŏr) Fullness. [L., fr. turgeo, to swell]

turgor

the cell state when it has taken in a maximum amount of water, causing distension of the protoplast. The term is used mainly in connection with plant cells, which have a maximum size when turgid that is governed by how much the cellulose cell wall will stretch. See WALL PRESSURE, PRESSURE POTENTIAL, TRANSPIRATION.
