Question

Plasma membranes engage in all of the following functions except: Cell to cell communication All of the choices listed are functions of the plasma membrane Sense extracellular stimuli Regulating exchange with extracellular fluid Cell adhesion Cell structural support

Answer 1

Answer:

All options are correct.

Explanation:

Plasma membrane or cell membrane is made up of lipid bilayer and proteins may span or insert in the lipid bilayer. Carbohydrates moieties are attached in association with lipids and proteins.

Cell membrane plays an important role in providing the structural support of the cell. The important molecules present on plasma membrane acts as signalling molecule in the cell to cell communication. The extracellular stimuli or change in the membrane fluidity is also performed by plasma membrane. The extracellular fluid exchanges regularly as plasma membrane is semi permeable membrane. The cell membrane also helps in the cell adhesion process.

Thus, all are the functions of plasma membrane.
