Throughout a stem, vascular bundles are organized with xylem and phloem and it runs lengthwise. The function of vascular bundles is to provide water, ions, and nutrients to all parts of the plant body. Fibers and tracheids are the components of vascular bundles that provide mechanical strength to stem. The bundles of the vascular tissues that run lengthwise through the mid of plant are known as vascular bundles.
