Question

Differentiate endarch and exarch vascular bundle

Answer 1

Explanation:

The main difference between endarch and exarch is that the endarch is the occurrence of protoxylem towards the center and metaxylem towards the periphery in the stem of the seed plants whereas exarch is the occurrence of protoxylem towards the periphery and metaxylem towards the center in the root of vascular plants.

Endarch and exarch are two types of primary xylem development in vascular land plants. Endarch arrangement results in the centrifugal pattern of development while the exarch arrangement results in the centripetal pattern of development.
