Sorry for not being there today. In the mean time here is what I want you to work on while I’m out.
Use the page number listed on your notes (puzzle pieces) to get the notes on active transport.
Then, watch the YouTube video on Active Transport (below) and take any additional notes and Highlight anything you already had. If you want to download the notes page and take notes on notability it can be found by clicking this link.
Then take the 10 question T/F Quiz
Finally, if there is time, answer the review questions with your table mates… or “tates” as I like to call them.
Today we’ll start section two of Unit 4 discussing Passive transport, or the movement of materials from high concentration to low concentration without the use of energy. There are three types of Passive Transport, all of which are related:
Diffusion: Movement of ANY material from High to Low concentration
Facilitated Diffusion: Diffusion of large materials that requires a transport protein to move across a membrane.
Osmosis: Diffusion of water across a membrane. In your cells, osmosis is a type of facilitated diffusion because it requires Aquaporins to move the water across the cell membrane.
For more information on this process please watch, and take notes on, the video below. When you are finished, please complete Directions of Osmosis Table (PDF) & the Passive Transport Review Questions (PDF).
