Verified by Toppr
The correct option is D Xylem with vessels All gymnosperms are perennial woody trees. Leaves are dichotomous and with parallel venation. Most gymnosperms lack vessels in their xylem (unlike flowering plants which have both vessels and tracheids), except for the order Gnetales, which have vessels.
So, the correct answer is option D.
