  • 15. 
    Read the passage carefully  A typical dicotyledonous embryo consists of an      i            and two     ii     . The portion of embryonal axis above the level of cotyledons is the epicotyl, which terminates with the     iii     or stem tip. The cylindrical portion below the level of cotyledons is hypocotyl that terminates at its lower end in the   iv       or root tip. The root tip is covered with a root cap. Embryos of monocotyledons possess only one cotyledon. In the grass family the cotyledon is called        v        that is situated towards one side (lateral) of the embryonal axis.At its lower end, the embryonal axis has the radical and root cap enclosed in an undifferentiated sheath called      vi           .  Choose the correct option
    • A. 

      I- plumule, ii-cotyledons, iii- embryonal axis, iv-radical, v- coleorrhiza, vi- scutellum

    • B. 

      I-embryonal axis, ii-cotyledons, iii-plumule, iv-radical, v-scutellum, vi-coleorrhiza

    • C. 

      I-embryonal axis, ii- scutellum, iii-plumule, iv-radical, v- cotyledons, vi-coleorrhiza

    • D. 

      I- radical, ii-cotyledons, iii-plumule, iv- embryonal axis, v-scutellum, vi-coleorrhiza
