How Support is Attained in Herbaceous Plants

Cells take in water and become turgid
They have specialized cells with high turgor pressure. When the cells are filled with water, the increased turgor pressure helps to keep the plant tissues rigid and upright.Turgor pressure is the pressure exerted by the cell contents against the cell wall.
Further, some herbaceous plants such as peas are climbers and use tendrils or other structures to attach to nearby objects or plants for support.

Explanation

Support in herbaceous plants is achieved through various adaptations and structural features that help them remain upright and resist the force of gravity. Unlike woody plants, herbaceous plants lack a strong, rigid, and permanent woody stem for support.
