During osmosis water passes through a semi permeable membrane from _____to _____.
All of the following involves osmosis except
Select the right option considering the below statements:
Statement I: When osmosis is demonstrated with a potato Osmoscope device, the sugar solution in the cavity of the potato becomes coloured and the level increases.
Statement II: This demonstrates that water entering the sugar solution through potato tissues acts as a selectively permeable membrane.
Assertion (A) : Bacteria do not burst in a hypotonic solution.
Reason (R) : They have a cell wall.
The osmotic theory was given by the two scientists _________ and ____________.

Osmosis
- When two solutions of different concentrations are separated from each other by a semipermeable membrane, the solvent from a low concentration solution begins to flow towards the one having a higher concentration.
- This process is called osmosis.
- Osmosis is functional as long as semipermeability of the membrane is taken into consideration.
- Hence, the spontaneous flow of solvent towards a solution across a semipermeable membrane is called osmosis.
- It involves the movement of solvent from its high concentration to its low concentration.
- It can also be said that osmosis is the special type of diffusion in which water molecules are the only molecules that diffuse because the presence of semipermeable membrane does not allow the movement of solute particles.
