Cell Membranes: Diffusion and Osmosis

Osmosis is the diffusion of water from an area of high concentration to an area of low concentration across a membrane. Cell membranes are completely permeable to water and the amount of water in the environment has a large effect on the survival of a cell. The picture shows a tube separated by a membrane and how the water moves from an area of ...

cell, molecules must pass through the cell membrane. Observing the diffusion process in real cells is difficult because they are too small to be seen easily. In this lab, you will make a giant model of a cell so that you can observe the effects of diffusion through a membrane. In your cell model:

Fundamentals of Membranes for Water Treatment

brane in which some molecules are small enough to fit through the pores while others are too large. Dialysis is the separation of smaller molecules from larger molecules in solution by selective diffusion through a semipermeable membrane. Dialysis tubing will be used in this laboratory to simulate a cell membrane. It is made of

MEMBRANES AND OSMOSIS INTRODUCTION Osmosis is the diffusion of water through a semi-permeable membrane in response to a concentration gradient. In Figure 1 a membrane or filter which allows free passage of water molecules but prevents the movement of glucose molecules is inserted between the beakers. Thus, the glucose molecules

Laboratory Activity #3 – Student Laboratory Packet

across the membrane. Water molecules sorb into the upstream face of the membrane, diffuse down the chemical potential gradient across the membrane, and desorb from the downstream face of the membrane. The second step, diffusion through the membrane, is the rate-determining step in water transport across the membrane.
