Bio-Report Essay, Research Paper 1.) Cellular Transport a.Osmosis Osmosis is the diffusion of water molecules across a differentially permeable membrane from a region where water molecules are more concentrated to one where they are less concentrated. The transport of water is simple the cell being selectively permeable will allow water through it until an equilibrium is reached and at that time water will flow both in and out of the cell maintaining the equilibrium.

Membrane Essay, Research Paper A Summary: Ion Channels in the Nerve-Cell Membrane In this article, Richard D. Keynes details the workings of ion channels in nerve cell membranes. Nerve impulses (action potentials) are the unit by which information travels in an organism?s nervous system, and the generation of this action potential is dependent on the nerve membrane being permeable to ions which in turn makes said membrane excitable.
