Cell Membrane: Structure And Function! Quiz

This quiz will ask you questions about cell membranes, their structure, and their functions. The membrane is the outside covering of a cell. Phospholipids make up the basic structure of a cell membrane. The membrane's primary function is to keep unwanted substances out of a cell and, at the same time, ensure the wanted substances can move in and out of the cell. Do take up this quiz and prove how much you know about this barrier in a cell.
