Question

Which of the following is characteristic of a monocot stem cross section?

A.vascular bundles that are only at the periphery of the cross section
B.vascular bundles that contain phloem only and no xylem
C.vascular bundles that are spread evenly among the parenchyma
D.vascular bundles that fill the entire cross section, leaving no room for parenchyma

Answer 1

The correct option is D. The vascular bundle in the monocot stem cross section are irregularly scattered in the ground tissue. At the periphery, the vascular bundles are smaller in size but they get bigger as one moves towards the center. The vascular bundle encloses both xylem and phloem and parenchyma is absent.
