in xylem we have two types they are the protoxylem and metaxylem.in a vascular bundle,if the arrangement in which the proto xylem is directed towards the centre and meta xylem elements towards the periphery it is an endarch xylem or endarch arrangement.this arrangement is found in the stems usually.

When protoxylem is towards the pheripery and metaxylem is faced inward, the arrangement is known as exarch.it is found in the roots usually.
