Answer:
The phospholipid bilayer, cell membrane, and plasma membrane are all synonomus terms for what surrounds a cell and in fact some structures inside the cell itself.
Explanation:
The cell membrane is a biological barrier that divides the inside of all cells from the extracellular space and protects them from their surroundings. A lipid bilayer, composed of two layers of phospholipids, makes up the cell membrane. Consider it as a bubble with two pieces of paper as its walls. On the inside of these two sheets of paper, there are molecules that don't like water, making them hydrophobic, and on the outside, there are molecules that do like water, making them hydrophilic, since they contact the extracellular space on the outside as well as the cytoplasm on the inside.
