HORTICULTURE

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 is a supporting tissue characteristic of the growing organs of many herbaceous and woody plants, and it is also found in stems and leaves of mature herbaceous plants, including those that are only slightly modified by secondary growth.

Detailed explanation-3: -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-4: -collenchyma, in plants, support tissue of living elongated cells with irregular cell walls. Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross section. The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells.

Detailed explanation-5: -Supporting tissues are formed of only one type of cells. They provide support and strength to the plants. They are of three types in plants: Parenchyma, Collenchyma, and Sclerenchyma. The connective tissue in humans connects various tissues or organs and acts as supporting as well as packing tissue.
