This article provides a diagram of monocot root. Also learn about:- 1. Exodermis 2. Origin of Lateral Roots 3. Root-Stem Transition. A monocotyledonous root has almost identical structure and plan of arrangement, of tissues, excepting the following points of difference: (1) Bundles in monocotyledonous roots are numerous and not limited, as in dicotyledonous roots; and the metaxylem cavities are wider. [...]
In this article we will discuss about the secondary growth in dicot root. Dicotyledonous roots have limited number of radially arranged vascular bundles. With the initiation of secondary growth some parenchymatous conjunctive tissue cells become meristematic beneath the phloem groups, thus forming strips of meristems equal to the number of phloem groups present. The cells of one-layered pericycle now divide. [...]
In this article we will discuss about the internal structure of dicot roots with the help of diagrams. I. Epidermis: It is single-layered and composed of thin- walled cells. The outer walls of epidermal cells are not cutinised. Many epidermal cells prolong to form long hairy bodies, the typical unicellular hairs of roots. Epidermis of root is also called epiblema [...]
