Very short answer question.
What is osmotic pressure?
Explain the term osmosis.
i. The pressure exerted due to osmosis is called osmotic pressure.
ii. Osmotic pressure is a pressure of the solution, which is required in opposite direction, so as to stop the entry of solvent molecules into the cell.
Osmotic pressure of a solution is equivalent to the pressure which must be exerted upon it to prevent flow of solvent across a semipermeable membrane.
