Revision Strategies:

• Retrieval practice drawing and labelling animal, plant and bacteria cells - Look, cover, write, check
• Make connections by explain the similarities and differences of diffusion, osmosis and active transport.

   2. How does the molecules movement change with temperature?
   3. Add dye to the water sample and watch the process of the dye diffusing in the water sample
   4. Add a new drop of dye and increase the temperature, what do you notice about the rate of diffusion?
   5. Add a new drop of dye and decrease the temperature, what do you notice about the rate of diffusion?
   6. Answer question 1

OSMOSIS - Interactive Video

1. Watch the video on osmosis and water potential

https://www.youtube.com/watch?v=L-osEc07vMs&feature=youtu.be

Summary

• Osmosis is the diffusion of water.
• In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower concentration is hypotonic. Solutions of equal solute concentration are isotonic.
• A contractile vacuole is a type of vacuole that removes excess water from a cell.

2. Answer the following questions

1. What is osmosis? What type of transport is it?
2. How does osmosis differ from diffusion?
3. What happens to red blood cells when placed in a hypotonic solution?
4. What will happen to a salt water fish if placed in fresh water?
