it regulates what materials enter and leave the cell
The Plasma Membrane of a Cell is used to separate the outside of the cell to the inside. The membrane is selectively permeable so that important nutrients and other substances can enter the cell but things like toxins can not
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.

Semipermeable or selectively permeable.
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
The plasma membrane (cell membrane).
Plasma membranes are selectively permeable.
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances
1. Protein Anchor 2. Selectively Permeable Barrier 3. Energy Production
Plasma (Cell) Membrane
Transport protiens
The main function of plasma membrane is to regulate things in or out of the cell cytoplasm by osmosis,active diffusion,passive diffusion,endocytosis,ectocytosis etc because it acts as selectively permeable membrane.Plasma membrane forms a barrier between the interstitial fluid and inside cell environment. It is selectively permeable. Plasma membrane has trans membrane proteins embedded in it.
