What materials are required to demonstrate exosmosis and endosmosis?

To demonstrate exosmosis and endosmosis, the following materials are required:

1. Two containers (such as beakers or cups)
2. Semi-permeable membrane (such as dialysis tubing or a piece of parchment paper)
3. Water
4. Solutes (such as salt or sugar)
5. Food coloring (optional, for visualization purposes)
6. Balance or scale (optional, for measuring changes in mass)

Materials for Exosmosis Demonstration:

- Semipermeable membrane (e.g., dialysis tubing, cellophane wrap)
- Two beakers or containers
- Distilled water
- Sugar or salt solution (higher concentration than distilled water)

Materials for Endosmosis Demonstration:

- Semipermeable membrane (e.g., dialysis tubing, cellophane wrap)
- Two beakers or containers
- Distilled water
- Specimen (e.g., potato slice, animal tissue, plant cell)
