Pericycle in monocot roots is involved in

In monocot roots, the pericycle (a layer of cells beneath the endodermis) is responsible for initiating lateral root primordia. Unlike dicot roots, monocot roots typically lack vascular cambium and do not undergo secondary growth (they have no secondary thickening). Option A is incorrect because cork arises from cork cambium in the cortex, not pericycle. Option B is incorrect because vascular cambium is absent in monocot roots. Option D is incorrect because monocot roots do not show secondary growth.
