Question

what is osmosis???????​

Answer 1

Answer

Osmosis is a process in which two solution of different concentration separated by semi permeable membrane diffusion of water take place from solution of lower concentration to solution of higher concentration.

• Osmosis always take place only in liquid.
• As per process movement of water molecule take place from lower concentration to solution of higher concentration.
• The pressure developed as a result of process called osmotic pressure.
• The process of opening and closing is affected by osmosis.

Types

There are two kinds of osmosis -

• Endosmosis
• Exosmosis

Endosmosis -

In endosmosis water landers cell from outer medium to plasma membrane.

Exosmosis -

In exosmosis water move from cell into outer medium through plasma membrane.

Osmotic Pressures - The maximum pressure which is developed in solution separated from its pure solvent is called osmotic pressure.

Answer 2

$\;\;\qquad\quad\quad\;\;\large{\underline{\underline{\bf{Osmosis:-}}}}$

Osmosis is a process by which solvent molecules (usually water) move from a region of low solute concentration to a region of high solute concentration, across a semi-permeable membrane. In this process, solvent molecules move down their concentration gradient, from a region of higher concentration to a region of lower concentration, until equilibrium is reached.

• A semi-permeable membrane is a barrier that allows some types of molecules to pass through it while restricting the passage of others. In the case of osmosis, the membrane is permeable to solvent molecules (usually water) but impermeable to solute molecules.

• When a semi-permeable membrane separates two solutions of different concentrations, the solvent molecules tend to move from the region of lower solute concentration to the region of higher solute concentration, in an attempt to balance the concentration of solutes on both sides of the membrane. This results in a net movement of solvent molecules across the membrane from the region of lower solute concentration to the region of higher solute concentration. This movement of solvent molecules continues until the concentration of solutes on both sides of the membrane is equal, at which point equilibrium is reached.

• The direction and rate of osmosis is determined by the concentration gradient of solutes on either side of the membrane, the permeability of the membrane, and the pressure exerted on the system. The pressure exerted on the system can be due to the presence of other solutes, such as in the case of osmotic pressure, or due to external forces, such as in the case of hydrostatic pressure.

• Osmosis plays an important role in various biological and physiological processes, such as the transport of water and nutrients across cell membranes, the regulation of fluid balance in cells and tissues, and the maintenance of blood pressure and kidney function in animals. It is also used in various industrial and technological applications, such as water purification, food preservation, and drug delivery.
