The mole is a unit of measurement that denotes an amount of substance (also called chemical amount). The mole is defined as the number of atoms found in exactly 0.012 kilogram (or 12 grams) of carbon-12, where the carbon-12 atoms are unbound, at rest and in their ground state.
Plasma Membrane Definition. Plasma membrane can be defined as a biological membrane or an outer membrane of a cell, which is composed of two layers of phospholipids and embedded with proteins. It is a thin semi permeable membrane layer, which surrounds the cytoplasm and other constituents of the cell.
Plasma Membrane The plasma membrane separates the internal environment of the cell from the external environment. It is made of phospolipids in which proteins are embedded Plasma Membrane Some of the proteins span the membrane and others do not. Some are on thin side surface of the membrane. Altogether, the proteins form a mosaic pattern. Plasma Membrane
