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.
