NEET BIOLOGY

Detailed explanation-1: -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-2: -Collenchyma cells have two main functions in plants, to provide flexible support to newly growing tissue and to fill in empty areas that will be later used for growth. Collenchyma are known for their living protoplast, unevenly thickened cell walls, and flexible nature. There are four main types of collenchyma cells.

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 cells are elongated cells with irregularly thick cell walls that provide support and structure. Their thick cell walls are composed of cellulose and pectin.

Detailed explanation-5: -Final answer: The flexibility in plants is due to Collenchyma tissue.
