Study Notes
Cell Walls
- Not all living organisms have cell walls. Examples include animals and many animal-like protists.
- Cell walls are non-living structures.
- They are located outside the plasma membrane.
- Cell walls provide shape, strength, protection, and support to the cell's protoplasm (the living matter inside the cell).
