selective permeability
The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.

Selective permeable
The cell membrane exhibits selective permeability, allowing it to control which substances can enter and exit the cell. This characteristic is primarily due to its phospholipid bilayer structure, which is embedded with proteins that facilitate transport. Small, nonpolar molecules can easily pass through, while larger or charged substances require specific transport proteins or channels. This selective control is essential for maintaining homeostasis within the cell.
Selective permeability is the characteristic of the cell membrane that allows only certain molecules and ions to enter or exit the cell. This feature helps regulate the internal environment of the cell by controlling what substances can pass through.
The main job of the cell responsible for controlling which substances enter and leave a plant cell is the cell membrane. It acts as a selectively permeable barrier, allowing nutrients and other essential substances into the cell while keeping unwanted substances out. Additionally, the cell membrane also helps maintain the cell's internal environment by regulating the movement of molecules.
The cell membrane controls which substances can and cannot enter a cell.
Substances pass through the plasma membrane, although ot is not technically an organelle.
