Cohesion simply means that water molecules like to stick to each other. 19. Water acts as a solvent. Where there is water there is life, and where water is scarce, life has to struggle or just "throw in the towel." lipids is the lateral diffusion of unbound water in the bilayer plane (x,y-plane) - it is because the diffusion is not confined by the periodic boundary conditions, whereas that perpendicular to the plane is. Many drops of water may remain on the penny because of the cohesive property of water. You'll see why water is so good at making things dissolve, making it an excellent solvent.
