Cell Membrane Permeability Names:_____. _____. Date:_____. Introduction : The Membrane of a cell is only two molecules thick, but it is of incredible importance in terms of the evolution of life on the planet as we know it. The plasma Membrane is composed of two layers of phospholipids, special molecules that Figure 1: Lipid are kind of confused, with a hydrophilic bilayer, with head group (the phosphate end) and a chemical hydrophobic tail end (made of fatty acid structures chains). These molecules organize into a indicated. Figure from bilayer, with the head groups facing Wikipedia, toward the outside and the inside of the accessed on cell, and the lipid tails pointing towards June 14, 2012. each other (Figure 1). The amphipathic nature of these molecules define the role of the Membrane , to allow for the separation of self from non-self and the specialization of organelles inside the plasma Membrane of the cell to perform functions that could otherwise be toxic to the cell.
