The ability for a plant and leaves to
remain firm and upright is known as
turgor pressure.
Turgor pressure occurs when the plant
cells of a plant exert force on the

plant’s cell wall, causing the plant to
stay upright.
A filled vacuole that stores water will
apply force to a plant’s cell wall,
causing the plant to stay upright. The
force of the vacuole must be greater
than the force of the cell wall.
When the force of the cell wall is
greater than the force of the vacuole,
wilting occurs. Wilting is the result of
a plant not receiving enough water and
nutrients, causing the plant to shrivel
and eventually die.
