Question

________gives mechanical strength of the plant

Answer 1

Answer:

Sclerenchyma tissue provides mechanical support to plant.

Answer 2

Sclerenchyma tissue provides mechanical support to plants.

Explanation :

๛ The tissue which provides support and mechanical strength to a plant or a growing organ in a plant is known as a mechanical tissue.

๛ Both the ground tissues- collenchyma (living) and sclerenchyma (dead) provide maximum mechanical strength to a plant.

๛ Collenchyma mainly provides mechanical strength to the growing plant parts.

๛ The cell wall of collenchyma is made up of pectin, hemicellulose, protein and cellulose.

๛ These thickening materials get deposited at the corners or at the tangential walls of collenchyma cells.

๛ It is a living cell which retains protoplasm even at maturity.

๛ Due to the presence of hydrated pectin in the walls of collenchyma cells, they also provide elasticity to the cell.

๛ Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants.
