Question

what is osmosis? explain in detail the process.​

Answer 1

Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes.

Answer 2

Answer

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

• Endosmosis- when a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes rigid.
• Exosmosis-when a substance is placed in a hypertonic solution, the solvent molecules move out of the cell and the cell becomes flaccid.

Osmosis is important for the cells for many reasons. It helps in the movement of important materials inside and out of the cell. The nutrients, water and other solutes move in and out of the cell by the process of osmosis.
