英文释义
名词 n.
-
Any plant possessing vascular tissue (xylem and phloem), including ferns, conifers, and flowering plants.
— By virtue of the presence and absence of vascular tissues, the tracheophytes and the bryophytes were also considered two distinctly different levels of anatomical organization. Largely for these reasons, the bryophytes and the tracheophytes are traditionally viewed as two distinct lineages, though they trace their evolutionary history back to a common ancestor.
