happens across a semipermeable membrane ONLY WATER Water is a small but extremely important molecule that makes up most of the liquid part of the cytoplasm in living things Deals ONLY. Learning Outcomes. explain what is meant by . passive transport . (diffusion and facilitated diffusion including the role of membrane proteins), . active transport. , . endocytosis . and . exocytosis;. Lab 4: Diffusion and Osmosis. PROBLEM . – What about physical pressure? . AIM: Describe the process of passive transport (diffusion across the membrane).. . It is easy to say that water will move from high concentration to low concentration…but look at the cell to the right…. Thinking Log. 15. . The cell membrane only lets certain things in. This is called being ____________ _____________.. 16. . Does diffusion use energy?. Answers. Thinking Log. 15. . The cell membrane only lets certain things in. This is called being . Facilitated Diffusion, Osmosis and Active Transport. Passive Transport. Learning Objectives. - explain what is meant by passive transport . - compare diffusion and facilitated diffusion . Identify the role of membrane proteins in transport. & . Osmosis. Why are diffusion and osmosis important?. Diffusion and osmosis are important because they provide . evidence. for the existence and movement of particles, that is, they provide . evidence. The Cell in its Environment. Ch 7, Section 2. L3 Biology. Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Diffusion. Movement of molecules from an area of high concentration to an area of lower concentration . Unit 2. Cytology. Passive Transport. Movement of substances across a membrane without any input of energy. 3 Types:. Diffusion . Osmosis. Facilitated diffusion. Move with the concentration gradient. Concentration Gradient. Facilitated Diffusion, Osmosis and Active Transport. Learning Objectives. To recap the process of diffusion.. To understand the concepts of facilitated diffusion, active transport and osmosis..
