Vedclass · Answer

(B) cell swells up when it is placed in a hypotonic solution.In a hypotonic solution,the concentration of water molecules in the surrounding medium is higher than the concentration of water molecules inside the cell.Due to the process of osmosis,water molecules move from the region of higher water concentration (outside) to the region of lower water concentration (inside the cell) through the semi-permeable plasma membrane.This net movement of water into the cell causes it to swell.
