The cell membrane is like a guard for the cell. It decides what can go in and out. Here’s how it works:
Selective Permeability: The cell membrane only lets some things pass through. It uses size, charge, and other qualities to make its choices.
Transport Proteins: Some things can’t enter or leave the cell by themselves, so special proteins help move them. These proteins act as channels or carriers.
Fluid Mosaic Model: The cell membrane is not stiff. It’s flexible and changes all the time. This helps it respond to different surroundings.
This control is really important because it keeps the cell healthy and working well!
