Experiment to Demonstrate the
Process of Osmosis with the help of Raisin
Requirements: Some Raisins, a bowl and water.
Procedure: Let a bowl be taken and make it half filled with water. Now Put araisin
in it and kept for observation.
Observation: After an hour it will be seen that the raisin becomes swollen byabsorbing
water from the bowl by the process of osmosis.
Explanation: Outside the raisin there was only water in the bowl. the cell wallof the
raisin is made of selectively permeable membrane and inside the cell there
present concentrate sweet juice (Sugar solution) Thus water enters inside
through the selectively permeable membrane, as a result the raisin has become
fully swollen.
