Lesson 9 - Membrane Transport
Lesson Objectives
Content Objective: Describe the differences between simple diffusion, facilitated diffusion, osmosis and active transport.
Language Objective: Create a venn diagram of simple diffusion, facilitated diffusion, osmosis and active transport.
Book Reference: 31 - 37
Syllabus Details:
Particles move across membranes by simple diffusion, facilitated diffusion, osmosis and active transport
The fluidity of membranes allows materials to be taken into cells by endocytosis or released by exocytosis.
Vesicles move materials within cells.
Application: Structure and function of sodium–potassium pumps for active transport and potassium channels for facilitated diffusion in axons.
