== Turgidity == {{main|Turgor pressure}} A plant cell in hypotonic solution will absorb water by [[endosmosis]], so that the increased volume of water in the cell will increase pressure, making the [[protoplasm]] push against the [[cell wall]], a condition known as [[turgor]]. Turgor makes plant cells push against each other in the same way and is the main line method of support in non-woody plant tissue. Plant cell walls resist further water entry after a certain point, known as full turgor, which stops plant cells from bursting as animal cells do in the same conditions. This is also the reason that plants stand upright. Without the stiffness of the plant cells the plant would fall under its own weight. Turgor pressure allows plants to stay firm and erect, and plants without turgor pressure (known as flaccid) wilt. A cell will begin to decline in turgor pressure only when there is no air spaces surrounding it and eventually leads to a greater osmotic pressure than that of the cell.<ref>{{Cite book|title=Plants in Action|last=Munns|first=Rana|publisher=Australian Society of Plant Scientists|year=2010}}</ref> Vacuoles play a role in turgor pressure when water leaves the cell due to [[hyperosmotic]] solutions containing solutes such as [[mannitol]], [[sorbitol]], and [[sucrose]].<ref name="[1]">{{cite journal|last1=Lang|first1=Ingeborg|last2=Sassmann|first2=Stefan|last3=Schmidt|first3=Brigitte|last4=Komis|first4=George|year=2014|title=Plasmolysis: Loss of Turgor and Beyond|journal=Plants|volume=3|issue=4|pages=583β93|doi=10.3390/plants3040583|pmc=4844282|pmid=27135521|doi-access=free|bibcode=2014Plnts...3..583L }}</ref> [[File:Plasmolysed Plant Cell.jpg|thumb|right|Plant cell undergoing Plasmolysis in a Hypertonic solution (x400 magnification)]]
