Question

what is osmosis ?(plzz asnwer it fast)

Answer 1

The movement of water from its high concentration to low concentration across the plasma membrane is called osmosis.

Answer 2

Osmosis is a process in which a fluid passes through a semipermeable membrane, moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute is present in high concentrations.

The end result of osmosis, barring external factors, will be equal amounts of fluid on either side of the barrier, creating a state which is known as “isotonic.” -
