  9. Water transport in plants

  10. What happens if the soil is salty? • We salt roads…how does this affect the nearby plants?

  11. Osmosis Lab: • We will set up an experiment to test the effects of different concentration sucrose solutions on plant cells & then determine the approximate concentration of sucrose in a given plant! • Use the websites provided on your labsheet to write an introduction!
