Cell Transport 3rd hour

Parts of the Cell Membrane Use the word bank below to identify the different parts of a cell membrane A = Carbohydrate ChainB = Lipid TailC = Phosphate HeadD = PhospholipidE = ProteinF = Phospholipid Bilayer Phospholipids are made up of a phosphate head and a lipid tail. The heads are hydrophillic because they like water and the tails are hydrophobic because they repel water Place the following into either active or passive transport Passive Transport Does not require energy Goes with the concentration gradient Molecules move from high to low concentrations Active Transport Does require energy Moves against the concentration gradient Molecules move from a low area of concentration to a high area of concentration Place each type of transport in either passive or active transport Passive Transport Osmosis Diffusion Facilitated Diffusion Active Transport Protein pumps Endcoytosis Exocytosis phagocytosis pinocytosis Match the type of transport with the appropriate definition Osmosis The diffusion of water from high to low Diffusion diffusion of molecules from high to low Facilitated diffusion diffusion that uses proteins to move large molecules Pumps Proteins that move molecules from low to high Endocytosis moves vesicles INTO the cell Exocytosis moves vesicles 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 Select the correct definition for each organelle. Organelle Definition cytoplasm jelly that holds everything in place ribosome makes proteins nucleolus makes ribosomes nucleus control center cell membrane allows things in of cell cell wall protection in plant cells mitochondria makes energy chloroplast makes food from sunlight smooth ER helps make lipids rough ER helps make proteins cytoskeleton provides support in the cell
