Hypothesis: Osmosis is defined by the Chambers Dictionary as the "diffusion of liquids through a semi-permeable membrane". According to Nelson Science: Biology, diffusion is "the net movement of particles from a region where they are at a higher concentration to a region where they are at a lower concentration". If a plant cell is immersed in water, water diffuses into the cell, through the cell wall and cell surface membrane and into the vacuole, until the cell wall stops the cell from swelling too much,...
