Plant Cell Foldable Enter the definition for Turgor Pressure into your plant cell foldable, then draw an example of high turgor and low turgor: Turgor Pressure: Pressure exerted by liquid in a plant cell vacuole that presses the cell membrane against the cell wall. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.
Turgor Pressure Turgor Pressure: a force exerted outward on a plant cell wall by the water contained in vacuole of the cell. Turgor Pressure pg 97 Cell Wall Vacuole
