Cell Transport What organelle is used to move substances in and out of the cell? Methods of cell transport are classified how? ________________ requires energy while ___________________ does not. Passive Transport When does diffusion occur? The range of concentrations is called the ___________________________. Define osmosis: Define equilibrium: A cell is in a ______________ environment when there’s a net movement out of the cell. A cell is in a _______________ environment when there’s no net movement. A cell is in a ________________ environment when there’s a net movement into the cell. Two types of Facilitated Diffusion What do carrier proteins do? Is facilitated diffusion an example of passive or active transport? What do ion channels do? Active Transport moves molecules _____________ the concentration gradient. The sodium-potassium pump is the process by which what occurs? Sodium ions are required _________ the cell while potassium ions are required ________ the cell. Define endocytosis: Cell Transport Define phaocytosis: What is a phagosome? Define pinocytosis: Define exocytosis: With a partner you must draw representations of a cell in a hypotonic, isotonic, and hypertonic solution in the three circles below. Label which is hypotonic, isotonic, and hypertonic. Lacey has a freshwater goldfish living happily in her aquarium. She is given a cool saltwater fish by her friend to keep as a pet and decides to let it live with her goldfish. Describe below specifically what will happen to the saltwater fish, using the terms cell membrane, concentration gradient, diffusion, osmosis and any other relevant terms. Then draw an illustration to clarify your writing. ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________________________________________
