Detailed explanation-1: -So, the correct answer is ‘Movement of water across a semi permeable membrane from an area of high water concentration to an area of lower water concentration’.
Detailed explanation-2: -The correct definition of osmosis is “ Movement of solute molecules from lower concentration to a higher concentration of solution through a semipermeable membrane”.
Detailed explanation-3: -Osmosis is a type of diffusion that, in biology, is usually related to cells. Diffusion is when molecules or atoms move from an area of high concentration to an area of low concentration. Osmosis is when a substance crosses a semipermeable membrane in order to balance the concentrations of another substance.
Detailed explanation-4: -In physiology, osmosis (Greek for push) is the net movement of water across a semipermeable membrane.[1][2] Across this membrane, water will tend to move from an area of high concentration to an area of low concentration.
