Angiosperms

Vedclass · Answer

(D) The presence of vessels and companion cells is a characteristic feature of the xylem and phloem tissues,respectively,in $Angiosperms$. While most $Gymnosperms$ lack true vessels (having tracheids instead) and companion cells (having albuminous cells instead),the order $Gnetales$,which includes genera like $Gnetum$,$Ephedra$,and $Welwitschia$,is an exception as they possess vessels in their xylem. However,the question asks for the presence of both vessels and companion cells. Companion cells are exclusively found in the phloem of $Angiosperms$. Therefore,$Angiosperms$ is the most appropriate answer as they possess both structures as a defining feature of their vascular tissue system.
