Explain how an upright position is maintained in herbaceous plants

Plant cells have a cellulose cell wall; which is rigid; plants absorb water through osmosis and cells become turgid; which makes the tissues firm and erect; Collenchyma cells have thickened cell walls; to give strength; Xylem vessels have thick and lignified walls; that strengthen plants.

Tracheids and fibres; in mature plants have dead thick lignified cells; for strength and support.

Parenchyma cells are round and tightly packed together; which maintains shape and firmness; of the plants.
