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 tissue consists of elongated cells with thick cell wall to provide mechanical support. It is mostly found in young stem and petiole of a leaf.

Detailed explanation-3: -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-4: -Collenchyma is common in climbing stems and can be detected in the epidermis of dicot stems and petioles. Collenchyma is a tissue that is made up of live and elongated cells with uneven cell walls.

Detailed explanation-5: -Collenchyma is seen only in herbaceous dicots.
