Arrange the following structures based on their location from the periphery to centre with respect to the anatomy of a dicotyledonous root. I. Pericycle II. Casparian strips III. Epiblema IV. Conjunctive tissue

Step-by-step solution

The outermost layer is epiblema. Many of the cells of epiblema protrude in the form of unicellular root hairs. The cortex consists of several layers of thin-walled parenchyma cells, with intercellular spaces. The innermost layer of the cortex is called endodermis. It comprises a single layer of barrel-shaped cells without any intercellular spaces. The tangential, as well as radial walls of the endodermal cells, have a deposition of water-impermeable, waxy material suberin in the form of casparian strips. Next to en
