ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness

Oak tree Surround the cells with a rigid wall that can withstand the pressure that builds up inside the cells dues to the inflow of water by osmosis. Paramecium Use contractile vacuoles to actively pump water out of the cells. Humans Surround the cells with an isotonic extracellular fluid. If 2 solutions have unequal concentrations of solutes‚ the solution with the higher solute concentration
