c. If a plant cell is placed in distilled water, the cell membrane will move away from the cell wall d. If a red blood cell is placed in a salt solution, salt will enter the cells, giving them a strange appearance e. Crenation is to plasmolysis as hemolysis is to turgor pressure 14. A small lipid molecule passes easily through the cell membrane.

The Model Cell. In order to understand how the Nernst equation is used to predict ion potentials, Nicholls et al present the model cell. In their model cell the cell membrane is only permeable to potassium and chloride and impermeable to sodium and an internal anion.

PEM Fuel Cell Technology. Proton exchange membrane (PEM) fuel cells work with a polymer electrolyte in the form of a thin, permeable sheet. This membrane is small and light, and it works at low temperatures (about 80 degrees C, or about 175 degrees F).

This Inside the Cell Membrane Video is suitable for 7th - 12th Grade. Without the cell membrane, our cells just couldn't keep it together! What else does this multifunctional membrane do? Take a deeper look at the fluid mosaic model using a video from an expansive biology playlist. Topics include embedded structures in the membrane and cellular transport.

One of the tenets of the Fluid-Mosaic membrane model is that the components of the bilayers are free to move. Before describing the differences between lipid and protein movement in the bilayer, it is important to consider the types of movement possible. Using a phospholipid as an example, the first type of movement is rotational.
