EVERYDAY SCIENCE

Detailed explanation-1: -Sclerenchyma is composed of dead cells. They provide mechanical support. Therefore collenchyma is living and provides mechanical strength to the plants.

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 cells are specialized plant cells that exist to provide strength and support and are found at the stem, roots and even seed coats of some plants.

Detailed explanation-5: -Sclerenchyma Characteristics It is a supportive tissue and is usually made up of dead cells with highly thickened lignified walls. It is mostly present in the mature parts of the plant.
