WebThe plasma membrane is also termed as a Cell Membrane or Cytoplasmic Membrane. It is a selectively permeable membrane of the cells, which is composed of a lipid bilayer and proteins. The plasma membrane is present both in plant and animal cells. Selective permeability is mediated by special proteins that traverse the cellular membrane. They are involved in the movement of ions and small molecules as well as large polymers such as RNA and proteins. This movement can be passive or active – with or without the expenditure of energy. For instance, ions are … See more Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for … See more Cell membranes are not easily visualized using light microscopes. Therefore, hypotheses about their existence only arose in the late 19th century, nearly two hundred years after the first cells has been observed.
