* Osmosis: Animal cells have a cell membrane that controls the movement of water. Water moves from areas of high concentration (like the surrounding environment) to areas of low concentration (like inside the cell) through a process called osmosis.
* Turgor Pressure: When water enters the cell, it creates pressure against the cell membrane, called turgor pressure. This pressure helps maintain the cell's shape and structure.
* Lysis: If the water intake is excessive, the turgor pressure can become too high. The cell membrane can stretch beyond its capacity, eventually bursting and causing the cell to die. This is called lysis.
Think of it like a balloon:
* Filling a balloon with air creates pressure.
* If you keep adding air, the balloon will eventually burst.
Factors affecting lysis:
* Concentration of water: The difference in water concentration inside and outside the cell influences how much water moves in.
* Cell membrane strength: Some cell membranes are more resistant to pressure than others.
* Presence of solutes: The presence of dissolved substances within the cell can influence the movement of water.
In summary: While water is essential for cell function, too much water can lead to cell lysis, disrupting the cell's internal environment and causing its death.
