6. Answer question 1

OSMOSIS - Interactive Video

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

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