Name two mechanical tissues which provide support in woody plants​
cricket20 [7]
<h2>Answer:</h2><h2>Sclerenchyma</h2><h2 /><h2>AND </h2><h2 /><h2>Collenchyma</h2>

Explanation:

<h3>The tissue which provides support and mechanical strength to a plant or a growing organ in a plant is known as a mechanical tissue. </h3><h3>Both the ground tissues- collenchyma (living) and sclerenchyma (dead) provide maximum mechanical strength to a plant.</h3><h3>Collenchyma mainly provides mechanical strength to the growing plant parts.</h3><h3>The cell wall of collenchyma is made up of- pectin, hemicellulose, protein and cellulose. </h3><h3>These thickening materials get deposited at the corners or at the tangential walls of collenchyma cells.</h3><h3>It is a living cell which retains protoplasm even at maturity.</h3><h3>Due to the presence of hydrated pectin in the walls of collenchyma cells, they also provide elasticity to the cell.</h3><h3>Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants.</h3><h3>So, the correct answer is 'Sclerenchyma and Collenchyma'.</h3>
