Cell membrane

say it: {sell MEM-brain}

Don't go on until you can say it.


Holding the whole thing together is the cell membrane.

Think of the cell as a plastic bag filled with jello. The cell membrane would be the plastic bag.

The cell membrane lets food pass into the cell and wastes pass out of the cell. If the cell membrane breaks, the cell dies.

In your workbook, answer these questions:

  • p. 3: What is the cell membrane and what does it do?

  • p. 4: If the cell membrane is a plastic bag, what is the jello?


Draw a cell membrane on your cell drawing on p. 3.
