Even though plants are rooted in the ground, they still move, exert
Correct
Force
,
and do
Correct
Work
.
Plant cells have very strong cell walls that allow
Correct
Pressure
to build up inside of the cell as water is absorbed. This pressure is called
Correct
Turgor pressure
.
When turgor pressure is high enough in a cell, the cell walls become
Correct
Firm
and
Correct
Straight
.
As a result, the cell becomes
Correct
Rigid
and the plant is able to stand tall and straight. When a plant does not get enough water, the turgor pressure inside of the cells
Correct
Decreases
.
A
Correct
Decrease in pressure
pushing against the cell wall causes the cells to lose their
Correct
Shape
and
Correct
Shrink
.
This causes the plant to begin to droop, or
Correct
Wilt
.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.
