Unit 5 Study Sheet Essential Questions ● What is the function of the cell membrane? ● What does selectively permeable mean, and why is it important? ● What are the key components of the cell membrane? ● What types of molecules can easily diffuse through the cell membrane? Which have more difficulty?How does the structure of the cell membrane affect its ability to control what enters and exits the cell? ● What is the process of diffusion? ● How does the concentration gradient influence diffusion across a membrane? ● What is osmosis? ● What is the difference between diffusion and osmosis? ● How does the concentration of solutes affect the direction of water movement during osmosis? ● What happens to cells when they are placed in hypotonic, hypertonic, or isotonic solutions? ● How does osmosis influence the shape and function of cells in plants and animals? ● What is passive transport? ● What are the three types of passive transport? ● What is active transport, and how does it differ from passive transport? ● What are some examples of active transport in cells, and how do they support essential life processes? ● What is an indicator? ● In the Regents lab, what molecules diffuse throug...
