Turgor pressure Transpiration is also crucial in maintaining water pressure within cells keeping them rigid so they can support the plant The water pressure inside plant cells is called turgor pressure and it is maintained by a process called osmosis

Plant Cell Growth and Elongation

Abstract Irreversible cell expansion is an essential process underlying plant growth and development Growth begins with cell wall loosening which induces wall stress relaxation which in turn generates the reduced water potential that is needed for water uptake and volumetric expansion of the cell
