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).

Step 1: iOS 7 – Bring up the toolbar from the bottom of your screen and TURN ON your DO NOT DISTURB Button

iOS 6 – Go to your settings and TURN OFF notifications or TURN ON do not disturb.

Step 2: If there are people sitting behind you facing you, set your iPad flat on your table; otherwise set your iPad up so that it faces you. Make sure your screen is bright enough to see from this angle.
