Question

why do xylem vessels are absent in gymnosperms and in pteridophytes?​

Answer 1

Answer:

Vascular bundles are present in the Gymnosperms but vessels are absent in the xylem and the phloem lacks the companion cells. The vessel element is typically found in the Angiosperms (flowering plants) and it is absent in the Gymnosperms as these plants do not produce flowers.
