Vedclass · Answer

(D) The terms $Exarch$,$Endarch$,and $Mesarch$ describe the arrangement of $Protoxylem$ and $Metaxylem$ in primary xylem based on the position of the $Protoxylem$ relative to the center of the organ.Secondary xylem is formed by the activity of the vascular cambium and consists of tracheids,vessels,xylem fibers,and xylem parenchyma.Since secondary xylem does not exhibit the differentiation into $Protoxylem$ and $Metaxylem$ seen in primary tissues,these terms are not applicable to secondary xylem.Therefore,the correct option is $D$.
