40 for original ! 1 ) explain how the surface area and volume of cells affect the rate of exchange of materials in and out of cells in multi cellular organisms. 2) ribosomes → rough endoplasmic reticulum → vesicle → golgi apparatus → vesicle → within the cell or outside the cell. explain where in this pathway the process of exocytosis plays a role. 3)the important factor in osmosis is not the number of molecules. instead, it is the number of particles in a given volume of solution. for example, one glucose molecule dissolved in water yields one particle, but one nacl molecule can yield two ions: na+ and cl-. water moves osmotically in response to the total concentration of particles in the solution. if there is a 10% glucose solution on one side of a semipermeable membrane and 5% salt solution on the other side, what will most likely happen to the flow of water?
