Osmosis

• What is a selectively permeable (semi-permeable)
  membrane?
•  
•  
•  
•  
• Allows some molecules through e.g. Visking
  tubing, cell membrane, etc.

3
Osmosis

• Describe how you carried out the investigation.
•  
•  
•  
•  
• Different solutions / Membrane / Observe / Time /
  Control /Measure /safety precaution

4
Osmosis

• How were you able to tell that osmosis had taken
  place?
•  
•  
•  
•  
• Tissue or membrane swollen / water movement

5
Osmosis

• State the result(s) of your investigation.
•  
•  
•  
•  
•  
•  
• e.g. heavier or swollen after

6
Osmosis

• Describe an investigation that you carried out to
  demonstrate osmosis.
•  
•  
•  
•  
• Membrane or plant tissue / two solutions
  indicated / different concentrations / result

7
Osmosis

• Describe how you demonstrated osmosis in the
  laboratory.
•  
•  
•  
•  
• Membrane or plant tissue / two solutions
  indicated / different concentrations / result

8
Osmosis

• Describe how you demonstrated osmosis as part of
  your practical activities.
•  
•  
•  
• Apparatus / type of membrane / dilute solution or
  (distilled) water / concentrated solution or
  tissue / time period / how change was observed /
  control
