Cell Membrane & Cellular Transport Practice

Cell Membrane Rap Review the video and then answer the provided questions to practice concepts associated with the plasma membrane and cellular transport. Amoeba Sisters: Cellular Transport Review the video and then answer the provided questions to practice concepts associated with the plasma membrane and cellular transport. Parts of the Cell Membrane Use the word bank (provided when you click in the blank to provide an answer) to identify the different parts of a cell membrane A = Carbohydrate ChainB = Nonpolar TailC = Polar HeadD = PhospholipidE = ProteinF = Phospholipid Bilayer Phospholipids are made up of a polar head and a nonpolartail. The heads are hydrophilic because theylike water and the tails are hydrophobic because theyrepel water. Match the part of the cell membrane with their function Carbohydrate Chain Helps ID the cell Protein Allow for larger molecules to pass through the cell membrane Cholesterol Provides stability to the cell membrane Phospholipid bilayer allows substances to move into and out of the cell Types of Transport IN DA CLUB - Crash Course Video Click the link to view the video from crash course before you begin the rest of the review. 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 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 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 How will the following diagram change over time? The water level for Solution A will increase and the water level for Solution B will decrease. The water level for Solution B will increase and the water level for Solution A will decrease. There will be no change in the water level. Which cell has been placed in a solution with a high amount of solute and low water concentrations? A B C Which cell has been placed in a solution with a low amount of solute and a high water concentration? A B C Which statement best describes the movement using the diagram? water will move into the cell water will move out of the cell there will be no movement of water the solute will move
