Question

What are the types of osmosis?
(a)Endosmosis
(b)Exosmosis
(c)Both (a) and (b)
(d)None the of the above

Answer 1

They are ways of osmosis, but one is the flow of water into a cell, and the other is the flow of water from a cell. One occurs when hypotonic solutions are stored in cells. The other arises in the positioning of cells in hypertonic solutions.

Complete answer:
The inflow and outflow of water molecules from the cell or body through a semipermeable membrane controls osmosis. The inflow of water or solvent is endosmosis, while the outflow of water or solvent from the cell through a semipermeable membrane is exosmosis.
Endosmosis- The water flows within a cell and swells if a cell is put in a hypotonic solution. This water movement within a cell is referred to as endosmosis. This arises because within the cytoplasm, the solute concentration of the surrounding solution is less than that.
Exosmosis- The water passes out of the cell when a cell is put in a hypertonic solution, and the cell becomes flaccid. This water movement out of the cell is referred to as exosmosis. This occurs because within the cytoplasm, the solute concentration of the surrounding solution is greater than that.

Additional Information: Osmosis is the spontaneous net movement of solvent molecules into a region of higher solute concentration through a selectively permeable membrane in the direction that tends to equalise the concentrations of the solution on both sides.
Three different types of solutions exist:
-Solution Isotonic
-Solution to Hypertonic
-Solution Hypotonic
One that has the same concentration of solutes both inside and outside the cell is an isotonic solution. A hypertonic solution is one that is outside the cell with a higher concentration of solute than within. The one that has a higher concentration of solute inside the cell than outside is a hypotonic solution.
so, the correct answer is ‘both (a) and (b)’.

Note: Significances of osmosis-
-The transfer of nutrients and the release of metabolic waste products are affected by osmosis.
-It is responsible for the soil absorption of water and conducting it through the xylem to the upper sections of the plant.
-It stabilises a living organism's internal environment by preserving the equilibrium between levels of water and intercellular fluid.
-It retains the cells' turgidity.
