Detailed explanation-1: -Collenchyma is observed as supporting tissue in growing organs of numerous herbaceous and woody plants, and in mature stems and leaves of herbaceous plants, including those starting secondary growth.

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 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: -Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

Detailed explanation-5: -Collenchyma is a tissue found in plant cells that help provide support and protection. It is considered part of the ground tissue (parenchyma) and it plays an important role in plants.
