do an activity of osmosis ( endo-osmosis and exo - osmosis) using raisins and write your observation
Answers
Answer:
Osmosis and Osmotic Pressure of the Solution
(i) Exo-Osmosis: The outward osmotic flow of water from a cell containing an aqueous solution through a semi-permeable membrane is called as Exo-osmosis. For example, egg (after removing hard shell) placed in conc. ... e.g., an egg placed in water swells up due to endo-osmosis.
Because water moved into the raisin, we know that the raisins' skins are semi-permeable membranes. During osmosis, water moves to an area of lesser water concentration. The raisins did not have very much water inside, so the water from the glass moved through the skin and filled the raisins.
Tea Bag Activity
Essentially, water flows (osmosis) through the tea bag (the permeable membrane) and the tea leaves dissolve (diffuse) throughout the water, turning the water brown The water also flows into the tea bag, seeking equal concentration.
How can you prove osmosis with the help of raisins experiment?
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.

Hope it's help you
Answer:
Endosmosis
when a cell is placed in a hypotonic solution the water moves inside a cell and swells this movement of water inside a cell is known as Indo Osmosis the happened because the solute concentration of the surrounding the solution is less than that inside the cytoplasm.
Exodmosis
when a cell is placed in a hypotonic solution the solution move out of the cell and the cell become flaccid this movement of water out of the cell is known as exo osmosis this happens because the solute concentration of the surrounding solution in higher than the inside the cell cytoplasm .
