    A)  cortex                 

    B)         pericycle                            

    C)         epidermis                          

    D)         endodermis                     

    Correct Answer: B

    Solution :

    Pericycle occurs between endodermis and phloem tissue. It is usually one to few layered and made up of parenchymatous cells. Lateral roots in higher plants originate from pericycle cells. During lateral root formation, at some places, the cells of pericycle become meristematic and form vascular cambium and phellogen which add the tissues to lateral roots.
