WebbWhat is said to make up the plasma (cell) membranes? What characteristics of the cell membrane determine what gets into the cell and what doesn't? Define lipids, phospholipids, and steroids and explain their functions; Cell membranes are made mostly of phospholipids (which contain fatty acids) that must maintain fluidity. WebbThe plasma membrane is the outer covering of all the cells but in a plant cell, it is present below the cell wall. It is made up of a phospholipid bilayer. Phospholipids are lipids with a phosphate group attached to them. The phospholipids have one hydrophilic head and two hydrophobic tails. The lipid bilayers have embedded proteins.
