Turgor

Definition

noun

(1) The state of being turgid; the rigid or fullness state of a cell due to high water content as a result of differing solute concentrations between a semipermeable membrane.

(2) The pressure produced by a solution against the semipermeable membrane enclosing the cell due to osmotic pressure differences between the inside and outside of the cell.


Supplement

Turgor is manifested in blood vessels, capillaries, and plant or animal cells. It plays a role in cell expansion and certain movements such as the closing or opening of stomata.It is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.


Word origin: Late Latin, from Latin turgēre, to be swollen.

Re: I want quick help

The cell wall of plant cells is strong and resembles reinforced concrete to withstand the turgor pressure of the cells. Turgor pressure is very important to support and maintain shape.

Weight gain of potato section in sucrose concentration

... not sure how much help that is, because there does not seem to be any correlation between the weight gain and the sucrose concentration, due to turgor pressure I suppose. Beaker Concentration of Sucrose (%) Weight of Potato Cube after 24 Hrs (grams) Percent Change in Mass (%) 1 0.0 13.4 34 2 ...

Vacuoles in Plants and Animals

... Why exactly plants have evolved to use a vacuole that is so big is probably a combination of using it to dump stuff and using it to maintain turgor. later the vacuole most likely evolved to also do the many complicated things it does nowadays...
