Answer 1

Answer:

According to the number of protoxylem groups roots may be monarch, as in Trapa natans, diarch, as in Lycopersicon, Nicotiana; triarch, as in Pisum; tetrach, as in Vicia, Cicer; pentarch, as in Ranunculus. Polyarch condition with many xylem groups is characters of monocotyledons.

Answer 2

The type of root will be Monocot root.

Reasons :

Monocot kind of root has polyarch type of vascular bundles. This means that there are more than 6 vascular bundles found in roots of monocot plants.

The pith is not small but large in the roots of monocots. Also, the pith is developed very well in them.

They lack cambium and so no secondary growth can happen in them.
