Cell Membrane
Structure in plant, animal, and neuron cells that holds everything together and allows certain things to pass into the cell and certain things to pass out of the cell. It also provides structural support for the cell.

there are different types of cell membranes, the one you're looknig for that only lets in certain things in is called a selectively permeable membrane.

the phospholipid bilayer. it is semi permebale, and uses diffusion (osmosis), active transport, and passive transport to let things pass in and out of the cell. It is made of a glycerol backbone, connected to two fatty acids, and a phosphate group. The phospholopid bilayer has a hydrophillic tail (likes water), and a hydrophobic tail (does not like water)
