    Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within cells, but water is perhaps the single most important molecule in any living system (Hayden and McNeil 2012). Since water molecules are so small, they are constantly going into and out of the cell. Osmosis is a situation where more water molecules are moving across the membrane in one direction than the other (Hayden and McNeil 2012). During osmosis the net movement of water molecules will be from a solution that has a lower osmotic concentration to a solution that has a higher osmotic concentration. When a solution has a higher concentration of solute within the cell than out, it is called hypertonic. When a solution has a lower concentration of solute within the cell than out, it is called hypotonic. And when there are equal concentrations inside and out of the cell, it is called isotonic. The relative osmotic concentration can be determined by a change in mass of the tissue.…

    The size of the surface must also be large enough to allow sufficient molecules to be transported to accommodate the metabolic processes in cell. For this reason, the surface area to volume ratio for any cell is critical. Size is also important in terms of width and length of a surface carrying out transport of materials. For example; the surface area of single-called alveoli in a person’s lungs, if spread out flat on a surface, would total the area of a football pitch.…
