OBJECTIVES -Describe and Draw Turgor Pressure -Complete Plant Cell Foldable -Set up Elodea demonstration
9
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.

10
Turgor Pressure
Turgor Pressure a force exerted outward on a
plant cell wall by the water contained in vacuole
of the cell.
