Roots absorb water through osmosis. Osmosis is the movement of water through a cellular membrane. During osmosis, water molecules move from a place of higher concentration to a place of lower concentration to create a balance. Roots work based on the principle of osmotic pressure. Water moves until there is an equal water pressure on either side of the membrane. A difference in pressure signals the plant to bring in water through the root cell walls.
