Answer: These are large epidermal cells located on the upper epidermis and help to bring about rolling of leaves under scarcity of water. The number of protoxylem poles in a root may be 1, 2, 3, 4, 5, 6 or more. Ex. General Cortex 4. Concentric vascular bundles. may contain tracheids, vessel elements, fibers, sclereids & parenchyma. The pulse located on the inside of the wrist, where the radial artery runs just beneath the skin; thumb side of … Asparagus stem). When xylem and phloem are arranged in the radius of the plant in alternative manner then it is called radial vascular bundle. But exceptionally, Ficus (Banyan tree) root is polyarch. A vascular bundle in which phloem encircles the central strand of xylem is called as amphicribral bundle, also known as hadrocentric bundle.
