What is the relationship between osmosis and turgor pressure?

Turgor pressure is caused by water pushing the against the cell wall of cells that have a cell wall (plant, , fungi etc.) moves water into or out of cells.

A turgid cell has a high turgor pressure because the large amount of water inside of the cell pushes the membrane against the inside of the cell wall.

A plasmolyzed cell has a low turgor pressure because there is a low volume of water inside of the cell.

This video explains why and how water moves into or out of cells by the process of osmosis.

Hope this helps!
