Cell Membrane & Cell Transport

Parts of the Cell Membrane Use the word bank below to identify the different parts of a cell membrane A = Carbohydrate ChainB = Hydrophobic Lipid TailC = Hydrophillic Phosphate HeadD = PhospholipidE = Channel ProteinF = Phospholipid Bilayer Phospholipids are made up of a phosphate head and a lipid tail. The heads are hydrophillicbecause the like water and the tails are hydrophobic because the repel (do not like) water Place each type of transport in either passive or active transport Passive Transport Osmosis Diffusion Facilitated Diffusion Active Transport Protein pumps Endcoytosis Exocytosis Match the type of transport with the appropriate definition Osmosis The diffusion of water from an area of high concentration to an area of low concentration Diffusion The diffusion of molecules other than water from an area of high concentration to an area of low concentration Facilitated diffusion A type of diffusion that uses proteins in order to HELP move large molecules across the cell membrane Pumps Proteins that move molecules against the concentration gradient (low to high). Requires energy Endocytosis A type of active transport that moves large molecules INTO the cell Exocytosis A type of active transport that moves large molecules OUT of the cell There are two types of endoycytosis. Pinocytosis is when you are moving liquids into the cell and phagocytosis is when you are moving solids into the cell
