Why are lycophytes considered vascular plants?

Lycophytes are classified as vascular plants because they possess a specialized vascular system composed of conducting tissues that transport nutrients and fluids throughout the plant body.1

Specifically, they contain:
* Xylem: Tissue responsible for transporting water and dissolved minerals from the roots to the leaves.21
* Phloem: Tissue that conducts food (carbohydrates) manufactured through photosynthesis from the leaves to other parts of the plant.21

These vascular tissues form a central column known as a stele within the plant axis. Because they possess these tissues, lycophytes are able to support true stems, leaves (specifically microphylls), and roots, which distinguishes them from nonvascular bryophytes.23
