Detailed explanation-1: -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-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 helps to provide strength to the plant’s stems, branches, leaves, and other structures. This strength allows plants to grow up without breaking from the weight of their own body. Collenchyma also provides a protective layer for plants that contain water-holding cells called hydrochomes.

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: -Collenchyma tissues are found below the epidermis of stem and around veins of leaves in plants.
