selective permeability
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
When a substance wants to enter a cell it goes through the cell membrane in a process called endocytosis.

selective permeability
The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit 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.
Through the use of proteins. Most substances pass through the membrane with the aid of a protein and changing the shape or the frequence of that protein determines how much of the substance can cross.
