A fresh Kolanut weighing 1g was put into salt solution. After 3 hour, the kolanut weighed 1.2g. This simple experiment demonstration that
- the salt solution is more concentrated that the cell sap of the kolanut
-
the cell sap of the kolanut is more concentrated than the salt solution
- the salt solution has the same concentration as the cell sap of the kolanut
- kolanut cell can multiply in water
- the kolanut lost some water molecules to the salt solution
