When maintain turgor pressure cells in both the leaves and stems of most non-woody or herbaceous plants contain?

To maintain turgor pressure, cells in both the leaves and stems of non-woody or herbaceous plants contain a high concentration of water within their vacuoles. This water creates internal pressure against the cell wall, keeping the plant rigid and upright. Additionally, the presence of solutes, such as sugars and salts, helps to retain water within the cells, further supporting turgor pressure. When turgor pressure is lost, plants may wilt and lose their structural integrity.
