![]() Nerve cell Gap between cells Cell membrane cell membrane Nerve cell To understand the function of anything in biology, you must study the structure first! Cell Membranes from Opposing Neurons (TEM x436,740). A cell membrane is also known as plasma membrane. Phospholipids Solution Pinocytosis Polar Solute Hydrophilic Solvent Exocytosis Hydrophobic Partially permeable Phospholipid bilayer Fluid mosaic model Surface area Glycoproteins Turgid Plasmolysis Passive transport Cholesterol Plasmolysed Proteins Selectively permeable Transport proteins Active transport Enzymes Carrier protein Receptor molecules Bulk transport Diffusion Endocytosis Concentration gradient Phagocytosis Facilitated diffusion Phagocytes Osmosis CrenatedĪll living cells are surrounded by a membrane. The cell membrane is the gateway into the cell. It is entirely clad in 100,000 square metres of inflated ETFE foil cushions arranged as an apparently random cellular structure.1 Cell Membrane: Structure and Function 6.2-6.3 The other major building on the site, built for the 2008 Summer Olympics, is the Beijing National Aquatics Center, also known as the Water Cube. ![]() Membranes are also used as non-structural cladding, as at the Beijing National Stadium where the spaces between the massive steel structural members are infilled with PTFE coated glass fiber fabric and ETFE foil. In these three kinds of structure, membranes work together with cables, columns and other construction members to find a form. The structural use of membranes can be divided into pneumatic structures, tensile membrane structures, and cable domes. ![]() Membrane structures are spatial structures made out of tensioned membranes.
