1. Objectives Define diffusion and osmosis. Explain passive transport by simple and facilitated diffusion. Explain the role of ATP and protein pumps in active transport across membranes. Explain how vesicles are used to transport materials. Describe how the fluidity of membranes allows it to change shape and reform during endocytosis and exocytosis. Outcomes 3: Describe different methods of transport across membranes. 5: Explain the difference between methods of transport across membranes. 7: Analyse the reasons different methods of transport are needed and when they may be used. Key terms: diffusion, osmosis, passive, facilitated, transport, protein pump, ATP

2. Using the document from earlier that we created go through and now try to answer each set of questions. Outcomes 3: Describe different methods of transport across membranes. 5: Explain the difference between methods of transport across membranes. 7: Analyse the reasons different methods of transport are needed and when they may be used. Key terms: diffusion, osmosis, passive, facilitated, transport, protein pump, ATP
