Cell Wall: The cells of plants, algae and fungi have thick, protective cell walls, which provide support, help maintain the shape of the cell, and prevent the cell from taking in too much fresh water and bursting.
Plasma Membrane: All cells, both prokaryotic and eukaryotic, have a plasma membrane, made mainly of phospholipids and proteins, which functions as a barrier, regulating the movement of materials between the inside and the outside of the cell.
