CELL BIOLOGY MEMBRANES AND PERMEABILITY 1. You have just placed an animal cell into a hypotonic solution. What does this mean? What would you predict to happen and why? How is this different than if you placed an animal cell in a hypertonic solution? Why? What would happen if you placed a bacterial cell into a hypotonic solution? Why is your answer different than for the animal cell? 2. You design an experiment to test the effect(s) various compounds have on the osmotic potential of a model cell. You know that substances dissolved in aqueous or gaseous solutions tend to diffuse regions of higher concentration to regions of lower concentration. You fill each of three (20 ml) dialysis bags half full with one of these substances: 5% by weight of glucose in distilled water 5% by weight of egg albumin (protein) in distilled water 5% by weight of glass bead (one glass bead) in distilled water The dialysis bag is permeable to water but impermeable to glucose, albumin, and glass bead. a.
