Question

Explain briefly the following osmosis

Answer 1

the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane is called osmosis.

Answer 2

$\large{\underline{\rm{\blue{Osmosis:-}}}}$

→ It is the spontaneous diffusion of water across a differentially-or semi-permeable membrane.

→ In plant cells, the cell membrane and the tonoplast are important determinants of movement of molecules in or out of the cell.

→ But the cell wall is not a barrier to movement as it is freely permeable to water and substances in solution.

→ Vacuolar sap in large central vacuole contributes to the solute potential of the cell.

→ The net direction and rate of osmosis depends on the pressure gradient and concentration gradient.

→ Water moves from its region of higher chemical potential to its region of lower chemical potential until equilibrium is reached.

→At equilibrium the two chambers should have the same water potential.
