Cell Transport Review

Ace cell transport! Review active, passive, osmosis, diffusion & more. Biology worksheet for 9th grade.

Phospholipids are made up of a phosphate head and a fatty acidtail. The heads are hydrophilic because the like water and the tails are hydrophobic because they do not like water. Match the part of the cell membrane with their function Carbohydrate Chain Provides stability and flexibility to the cell membrane Protein Allow for larger molecules to pass through the cell membrane Fluid Mosaic Model term used to describe the cell membrane since it is NOT rigid and is made of many different parts Types of Transport Place the following into either active or passive transport Passive Transport Does not require energy Molecules move from high to low concentrations Moves with the concentration gradient Active Transport Does require energy Moves against the concentration gradient Molecules move from a low to high 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, such as oxygen, 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 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 Which of the following is not a type of passive transport? Osmosis Facilitated diffusion Endocytosis Diffusion A blue food coloring tablet is placed in a cup of vinegar and water. After several seconds, the blue tablet will begin to dissolve and will eventually spread evenly throughout the liquid. Draw an ARROW to illustrate the movement of molecules. 1. The blue dye is traveling from _ a to a _ concentration.2. Identify the type of transport illustrated in this scenario.3. Does this movement of particles require energy? Use the diagram and scenario above to answer the questions. Draw arrows to show the movement . Fill in the blanks using the diagram above. 1. Solution A is a hypotonicsolution.2. Solution B is a hypertonic solution.3. Osmosis would occur from solution A→ solution B4. Diffusion would occur from solution B→ solution A Answer the questions based upon the scenario. A cell contains 10% Potassium. The solution, containing the cell, has 85% Potassium.a. Is the starting solution Hypo compared to the cell? Hypertonicb. Is the starting cell Hypo compared to the solution? Hypotonicc. What will happen to the cell – SHRINK, SWELL, or STAY THE SAME? Shrink
