Examples include non-timber plants where osmosis allows plant cells to collect water and become sufficiently plump so that the plant can stand on its own two feet. It has been claimed by some investigators that the positive hydrostatic pressure developed in the xylem vesselsroot pressureunder conditions of excess absorption and low transpiration may be adequate to push the water to the tops of small herbs or shrubs. Positive pressure inside cells is contained by the cell wall, producing turgor pressure, which is responsible for maintaining the structure of leaves; absence of turgor pressure causes wilting.
