CELL WALL AND CELL MEMBRANE
CELL WALL
- They are only found in plant cells.
- They have an outer layer that's rigid, strong, and stiff.
- Made of cellulose
- They support (grow tall)
- Allows water ,oxygen and carbon dioxide to pass into and out of cell.
- Provides protection
CELL MEMBRANE
- They are found in both plant and animals cells.
- Plant - cell membrane is inside cell wall
- Animal - cell membrane is the outer layer
- phospolipid tails
- bilayer
- protein channels
- They support and protect the cell
- Controls movement of materials in and out of cell.
- Barrier between cell and its environment and maintains homeostasis
