Eukaryotic Plasma Membrane

The plasma membrane in eukaryotic cells is responsible for controlling what gets into and out of the cell. A series of proteins stuck in the membrane help the cell communicate with the surrounding environment. Among other things, this communication can include
Sending and receiving chemical signals from other eukaryotic cells
 
Interacting with the cells of prokaryotic organisms during the process of infection.
