Plant Stand
Posted in Longberger | Comments OffHow does a plant stand up straight and not wilt? What mechanism controls this?
Is this something to do with storing waste and left-over energy? I know the plant has the ability to stop photosynthesizing----> Does this have anything to do with how the plant stays upright?
Plant cells have unique structures that are different from other organisms such as Cell Wall and Vacuole.
Cell Wall in plant cell is mainly compose of cellulose (polysaccharides) which gives cell the rigidity and strength for standing up straight as well as wilt (seen in stems and leaves).
Vacuole in plant cell has several important function such as store waste products and water. The water inside vacuole helps the cell maintains its tugor pressure. Turgor pressure also gives the cell wall rigidity.
So Cell Wall and Vacuole are important structures that help the plant stand up straight, but also "wilt" because the rigidity helps the cells bend (this is why leaves and stems can bend).
