Introduction
Outer most covering of the cell is called Cell Membrane
Pre-Requisites:
Cells have organelles to perform specific functions.
Activity:
Use of Compound microscope to view the cell membrane. Put raisins (dried grapes) in water, it will gain water. When placed in solution of sugar or salt, it loses water and shrinks.
Real Life Question:
How does substance get in or move out of the cell? How does movement get place in the cell? How does the cell prevent the movement of unwanted material into the cell?

| Every living cell | The cell membrane act as selectively permeable allows and permits the entry and exit of materials. |
What you learn in Theory:
Cell is covered by a selectively permeable membrane. What is cell membrane and how does it function?
What you learn in Practice:
How this selectively permeable membrane does acts as a gate to enter or exit the cell.
