The plasma membrane's function is that it allows substances to enter or leave the cell. Its importance is that it acts as a boundary, holding the cell constituents together and keeping other substances from entering. It is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to.


The plasma or cell membrane is made up of a double layer of phospolipid molicules with holes through it made from proteins.
