Answer» Correct Answer - A Dictyledonous stems usually show secondary growth in thickness, which id due to the activity of vascular cambium and cork cambium. Vascular cambium is present between phloem and xylem. Such vascular bundles because of the presence of cambium prossess the ability to form secondary xylyem and phloem tissues, and hence exhibit secondary growth.
