	The Cell Membrane  Paul Andersen gives you a brief introduction to the cell membrane. He starts by describing amphipathic nature of a phospholipid and how it assembles into a membrane. He gives an overview of the fluid mosaic model inside cells. He also discusses the movement of material across a membrane and the role of proteins in movement and function. 2012年02月26日再生回数 3226
	Plasma Membranes: The Boundaries of Life  Our Cell Membranes program begins by examining cell wall structure and the major functions of cellular membranes before introducing the fluid mosaic model of the phospholipid bilayer, and transport, recognition, and receptor proteins. The concepts of simple and facilitated diffusion, passive and active transport, and osmosis are illustrated. Endocytosis and exocytosis, the role of contractile and central vacuoles, and how desmosomes and tight junctions tie cells together and how plasmodesmata and gap junctions facilitate communication are explained. 2010年10月20日再生回数 5454
	Cell wall and Plasma Membrane are Two Distinct Structures  Check us out at www.tutorvista.com A cell wall is a tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection, and also acts as a filtering mechanism. A major function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. They are found in plants, bacteria, fungi, algae, and some archaea. Animals and protozoa do not have cell walls. The materials in a cell wall vary between species, and in plants and fungi also differ between cell types and developmental stages. In plants, the strongest component of the complex cell wall is a carbohydrate called cellulose, which is a polymer of glucose. In bacteria, peptidoglycan forms the cell wall. Archaean cell walls have various compositions, and may be formed of glycoprotein S-layers, pseudopeptidoglycan, or polysaccharides. Fungi possess cell walls made of the glucosamine polymer chitin, and algae typically possess walls made of glycoproteins and polysaccharides. Unusually, diatoms have a cell wall composed of silicic acid. Often, other accessory molecules are found anchored to the cell wall. The plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. In the case of the plasma membrane, these compartments are the ... 2010年05月05日再生回数 6022
