Cell membranes
A cell membrane is also known as a plasma membrane. It allows substances to enter and leave the cell.
Proteins do a number of things in the cell membrane. For example, they send and receive signals to other cells and act as a gate.
Carbohydrates are usually in the form of chains they are attached to proteins atop the membrane. They act as adhesion and address loci for the cell.
Phospholipids are the outermost layer of the membrane. They attract water.
Phospholipid tails are inside the layer of the membrane. They're attached onto the heads and they repel water out.
