Detailed explanation-1: -So, the correct answer is ‘Sclerenchyma’.
Detailed explanation-2: -Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
Detailed explanation-3: -Xylem provides maximum mechanical strength.
Detailed explanation-4: -Sclerenchyma are composed of long, narrow cells. This provides strength to plant parts.
Detailed explanation-5: -6.3.2.3 Sclerenchyma Tissue Sclerenchyma tissue, when mature, is composed of dead cells that have heavily thickened walls containing lignin and a high cellulose content (60%–80%), and serves the function of providing structural support in plants.
