    October 12, 2012  Diffusion and Osmosis Shown In Solutions Section 1: Abstract This lab, title Diffusion and Osmosis, was centered around the diffusion across a cellular membrane and how exactly materials move and diffuse in concentrations. Both diffusion and osmosis are forms of movement that are part of passive transport dealing with cell membranes. Diffusion is where the solutes move from an area of high concentration to a low concentration. Water goes through the cell membranes by diffusion. Osmosis is...

     Introduction A computerized simulation experiment will be conducted in order to study the cell transport mechanism via the cell’s selectively permeable membrane and passive processes of simple and facilitated diffusion. The plasma membrane is a gateway which allows nutrients to enter the cell and keep undesirable substances out, hence, making it selectively permeable. One method of transport is called active transport, which uses ATP to transport substances through the membrane. The other is...

    Diffusion and Osmosis Lab Introduction: 1) The relationship between the rate of diffusion, volume and surface area is that the surface area of a subject somewhat correlates with the volume of the object. When the surface area and volume are set up as a ratio, this gives a good idea as to how fast the rate of diffusion will be. The higher surface area to volume ratio, the faster the rate of diffusion. This is because then there is more surfaces to diffuse through and there materials to diffuse...
