Question

Four radial vascular bundle are found in

(a) dicot root

(b) monocot root

(c) dicot stem

(d) monocot stem.

Answer 1

(a) dicot root

The plant tissue of the basis is defined by radial arrangement of vascular bundles i.e., vascular tissue and bast occur in separate patches on alternate radii. The numbers of vascular tissue and bast teams vary from 2 to 6. however tetrarch condition (four vascular bundles) is additional common. monocotyledon root usually has over six vascular bundles (polyarch). vascular bundles in exogen stems ar joint, collateral or bicollateral, endarch and open. they're organized in an exceedingly ring.

In monocotyledon stems the vascular bundles ar joint, collateral, endarch and closed. they're scattered within the ground tissue.
