Detailed explanation-1: -Final answer: The flexibility in plants is due to Collenchyma tissue.

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: -Collenchyma is a type of permanent tissue. It allows easy bending of plant parts without their breakage. It provides mechanical support to plants thus it provides flexibility to plants. It is present in leaf stalks below the epidermis.

Detailed explanation-4: -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-5: -Collenchyma is an elastic, living mechanical tissue. The cell wall of collenchyma contains cellulose, hemicellulose, and pectin which makes the cell wall thick at the corner and provides strength to the walls. They provide mechanical support to the growing parts of the plants.
