Cell Transport 5th Hour

Master cell transport! Understand active vs passive processes like osmosis and diffusion.

Parts of the Cell Membrane 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 an area of high concentration to an area of low concentration Active Transport Requires energy Moves against the concentration gradient Molecules move from an area of low concentration to an area of high concentration Place each type of transport in either passive or active transport Passive Transport Osmosis Diffusion Facilitated Diffusion Active Transport Protein pumps Endocytosis Exocytosis phagocytosis pinocytosis Match the type of transport with the appropriate definition Osmosis The diffusion of water from high to low Diffusion movement of molecules from high to low Facilitated diffusion diffusion that uses proteins to move molecules from high to low 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
