Web26 aug. 2024 · Xylem and phloem travel entire length of stems in discrete threads called ‘vascular bundles’. In eudicots, vascular bundles are arranged in a ring within the stem. Each vascular bundle is orientated with the xylem on the interior and the phloem on the outside of the xylem. WebStems. The tissues of the stem, as with the other organs, are organized into three tissue systems: dermal, vascular, and ground tissue systems.Below you can see how the tissue systems are arranged in the stem.

WebSuccessive year’s growth of vascular tissue adds layers of xylem to the stems of woody plants. These are referred to as growth rings with the outermost ring being the youngest. The outermost layer of the stem is the cortex or bark; the bark is produced by a meristem called the cork cambium. WebAnatomy of Salvadora Stem: Epidermis: The single-layered epidermis consists of barrel-shaped cells, and remains covered with a very thick cuticle. Cortex: The cortex includes thin-walled parenchyma cells. Below the epidermis few layers of thin-walled parenchyma cells represent hypodermis.
