a. monocot leaf
b. dicot leaf
c. dicot stem
d. monocot root

Answer 1

The polyarch condition is found in monocot root.

In the monocot roots, the vascular bundles are radially arranged.

And the polyarch condition is the one in which many bundles of xylem is present.

The xylem and phloem in the vascular tissue of the monocot roots occur alternatively.

In between this radial arrangement has a pith in the centre which is either parenchymatous or schelrenchymatous.

More than six vascular bundles are present which impart the monocot roots a polyarch condition.
