Visualising Osmosis & Diffusion Investigation
Product Code : JLI-BLE-10589
Quick Answer: The Visualising Osmosis & Diffusion Investigation demonstrates selective permeability with a model cell and a mixture of coloured dye solutions: one dye passes through the membrane while the other stays inside. It is designed for a class of 40 students.

Key Features
- Model cell and special dye solutions.
- Colour change shows one dye passing the membrane while the other is retained.
- Links osmosis and diffusion to the passive transport of water through the cell membrane.
- Shows how a cell absorbs nutrients and discharges wastes.
- Class size: 40 students.

How It Is Used
Students start with the model cell and the mixed dye solutions and observe which colour passes through the membrane. The result is used to explain selective permeability and how osmosis and diffusion keep a cell in equilibrium.
Frequently Asked Questions
What does the Visualising Osmosis & Diffusion Investigation show?
Selective permeability: the model cell's membrane lets one dye pass while the other stays inside, giving a clear colour change.
How many students is the Visualising Osmosis & Diffusion Investigation for?
It is sized for a class of 40 students.
