Practice question

Amborella xylem lacks vessel elements; water conduction exclusively via narrow tracheids with bordered pits circular lacking torus-margo complex simple, providing hydraulic safety against freeze-thaw embolism in cloud forest understory montane habitat. Absence perforation plates contrasts with most angiosperms possessing simple perforation plates significantly reducing resistance and increasing efficiency. Companion cells present in phloem but not xylem, secondary growth limited diffuse porous. Possession tracheids only interpreted as ancestral retention predating vessel evolution arising multiple times, not secondary loss. Statement lacks both xylem phloem incorrect because vascular tissues present, companion cells belong phloem not xylem, vessels only opposite description of reality.
