Question

xylem in root is exarch or endarch??​

Answer 1

ANSWER :-

In roots, the xylem is exarch or centripetal, which means that the protoxylem (the xylem that formed first), is found lying towards the periphery.

Extra Information-

• The central column of axis (including the root and the stem) is called stele, which is made up of a number of vascular bundles, which constitute the vascular tissue system.
• The vascular bundle consists of xylem, phloem and cambium.
• The cambium is not present in all cases but it is considered to be a part of the vascular bundle in cases where it is present.
• The xylem may either be endarch or exarch.
• In stem, the xylem is endarch or centrifugal, which means that the protoxylem (the xylem that formed first), is found lying towards the centre (the centre is also known as the pith).
