Experiment Questions Osmosis

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

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

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

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

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

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

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

Visking tubing or named plant tissue Osmosis What did you use as the selectively permeable membrane in your investigation of osmosis? Visking tubing or named plant tissue
