How would you describe turgor?
Turgor, Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor 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.
How would you describe skin turgor in nursing?
Skin turgor is the skin’s elasticity. Its ability to change shape and return to normal may be decreased when the patient is dehydrated. To check for skin turgor, gently grasp skin on the patient’s lower arm between two fingers so that it is tented upwards, and then release.
What do you know about turgor pressure?
Turgor pressure is the hydrostatic pressure in excess of ambient atmospheric pressure which can build up in living, walled cells. Turgor is generated through osmotically driven inflow of water into cells across a selectively permeable membrane; this membrane is typically the plasma membrane.
What is increased turgor?
Turgor pressure’s actions on extensible cell walls is usually said to be the driving force of growth within the cell. An increase of turgor pressure causes expansion of cells and extension of apical cells, pollen tubes, and in other plant structures such as root tips.
What is positive skin turgor?
What is skin turgor? Skin turgor refers to the elasticity of your skin. When you pinch the skin on your arm, for example, it should spring back into place with a second or two. Having poor skin turgor means it takes longer for your skin to return to its usual position.

What is an example of turgor pressure?
Think of a balloon that is being filled up with water as a turgor pressure example. The balloon swells as more water draws in. The pressure that the water exerts against the walls of the balloon is similar to the turgor pressure exerted against the wall.
Is turgor pressure positive or negative?
It is also known as wall pressure or turgor pressure. The pressure potential is usually positive in a turgid plant cell. It is negative in xylem tissues and is a potential pressure in a transpiring plant.
What does skin turgor measure?
