Cells
Plasma/Cell Membrane
Not a solid structure, made of millions of smaller molecules that create a flexible and porous container.
Function
Keeps the pieces inside
Present in
Both
Cell Wall
Cell walls are made of special sugars called cellulose, They provide protective frame work for the cell to survive.
Function
Protection and Support
