Osmosis in potato cylinders template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
Potato cylinders of equal size in boiling tubes of 0 to 1.0 mol dm⁻³ sucrose in a rack; weigh before and after. Plot % change in mass against concentration. GCSE / high school; A-level / AP / IB Biology.
What the template shows
- Find the sucrose concentration with the same water potential as potato tissue
- Cylinder takes in water by osmosis: gains mass, firm
- Potato cylinder
- Cork borer, then cut to the same length with a scalpel on a tile (blade away from fingers); blot dry and weigh each
- Sucrose series
- 0, 0.2, 0.4, 0.6, 0.8, 1.0 mol dm⁻³, same volume in each; label the tubes
- Water leaves: loses mass, soft
- Leave at least 30 min, blot, reweigh. Where % change = 0, the solution matches the cells. Visking tubing of sucrose is a model variant
- Reaction setup
Drawn with 15 shapes – every one editable in MolDraw.
