Turgor Pressure

Goal: I will be able to explain why turgor

pressure is important to plant cells.

Markets spray their

vegetables with water, why?

Turgor Pressure

If the concentration of water is more outside a plant cell than inside water will enter the cell by osmosis

This fills up the cytoplasm and vacuole causing the plant cell to swell up against its cell wall

This outward pressure is called

turgor pressure

Under normal conditions

Under normal conditions turgor pressure

supports the plant keeping their stem and

leaves rigid

High concentrations of

solute outside the cell

Cause the water in the plant cell to

escape to create a balanced

concentration.

This causes the cytoplasm to pull

away from the cell wall and the

plant wilts and dies.

Question 1: What prevents a plant cell from bursting when it is full of water?

Question 2: What will happen to an animal cell when it is placed in distilled water? Why?

Question 3: Based on what you’ve learned about osmosis, explain why grocery stores spray their vegetables with water.
