Important Points
| Turgor pressure |
Turgor pressure is exerted by fluid in a cell that presses the cell membrane against the cell wall. Fungi, protists, bacteria, and plants all secrete various extracellular molecules form together to create a solid wall on the outside of their cells. As water fills the cells, it pushes against the cell membrane and cell wall, producing turgor pressure. |
| Osmosis |
It is a process where a weaker saline solution will tend to migrate to a strong saline solution. Examples of osmosis are when plant roots absorb water from the soil and our kidneys absorb water from our blood. |
| Cytolysis |
It is also known as osmotic lysis, which occurs when a cell bursts and releases its contents into the extracellular body due to a large influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume. |
