Cell Membrane (Plasma Membrane)
What does it do?
The cell membrane is a thin, flexible skin just inside the cell wall. It controls what goes in and out of the cell — like a security gate. Only the right things are allowed through!
Think of it like...
Think of it like the doors and windows of a house. They let fresh air and people in, but keep out rain, bugs, and burglars.
🌟 Fun Fact
The cell membrane is so thin you'd need to stack about 10,000 of them to be as thick as a single sheet of paper!
