Detailed explanation-1: -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-2: -petiole of leaf is made up of Collenchyma.

Detailed explanation-3: -A petiole attaches the leaf to the stem and contains vascular tissue that provides a connection from the stem to permit sap to enter the leaf and the products of photosynthesis (carbohydrates) to be transported from the leaf to the rest of the plant.

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: -Veins run through the leaf’s mesophyll layers. Veins connect the vascular tissue of the stem to the photosynthetic cells of the mesophyll via the petiole and are made up of vascular tissue, xylem, and phloem.
