1. Turgor Pressure

2. The pressure exerted by water inside the cell against the cell wall.
Turgor Pressure-
The pressure exerted by water inside the cell against the cell wall.

3. Plant Cell

4. How does turgor pressure affect plants?
The central vacuole fills with water getting bigger and bigger.
This pushed the organelles and cytoplasm into the cell wall.
The cell wall then becomes very rigid as a result of the turgor pressure.
This rigidity allows a plant to stand up.
Without turgor pressure plants would always look wilted and would never stand up straight.

6. Tropism
Tropism is a response of a plant to a environmental stimulus.

7. Tropism
Types of tropism:
Phototropism
Hydrotropism
Geotropism

8. Phototropism A tendency of plants to grow towards a source of light

9. Phototropism

10. Hydrotropism
The positive or negative movement of growth as a plant root moves toward, or away from moisture.

11. Geotropism
Any positive (or negative) movement or growth of a plant or sessile animal in response to (or against) the force of gravity.
