What the PowerPoint covers
- What osmosis is: water moving from high to low water potential through a partially permeable membrane.
- Osmosis and plant cells: turgid and plasmolysed cells, with diagrams.
- Osmosis and animal cells: lysis, no change and crenation in dilute, isotonic and concentrated solutions.
- Required practical: measuring osmosis in potato cylinders, from method to conclusion.
- Key vocabulary and exam tips: turgid, flaccid, plasmolysis, lysis and how to use water potential correctly.
Who it is for
GCSE biology and combined science students (Foundation and Higher) revising Cell Biology, and teachers who want a ready made summary for a recap starter, homework or revision lesson. Written for the AQA specification, and just as useful for other exam boards.
