Key Stage 3
Meaning
The cell membrane is a layer covering the cytoplasm of a cell.
Function
About Cell Membranes
- In an animal cell the cell membrane is the outer layer of the cell.
- In a plant cell the cell membrane is protected by a cell wall on top of it.
The cell membrane of an animal cell is the outer layer. | The cell membrane of a plant cell is protected by the cell wall. |
Key Stage 4
Meaning
The cell membrane is a partially permeable membrane covering the cytoplasm of a cell.
Function
About the Cell Membrane
- In an animal cell the cell membrane is the outer layer of the cell.
- In a plant cell the cell membrane is protected by a cell wall on top of it.
- The cell membrane only allows in certain molecules. This is referred to as a partially permiable membrane. This means some molecules, like water, can diffuse in and out of the cell, however, some cannot pass into the cell.
