Plant Classification Vascular Tissues Tracheophytes are characterized by the presence of vascular tissue, composed of specialized conductive cells that create "tubes" through which materials can flow throughout the plant body. These vessels are continuous throughout the parts of the plant, allowing for the efficient and controlled distribution of water and nutrients. In addition to this transport function, vascular tissues also provide a measure of support to the plant, contributing to tracheophytes' ability to grow much larger and higher than nonvascularized plants. The two types of vascular tissue are xylem (dead cells) and phloem (living cells). Roots and root hairs, through which the bulk of water and minerals enter the plant body, are also integral to the vascular system of tracheophytes. Xylem and Phloem Xylem consists of a "pipeline" of dead cells arranged end to end for water and mineral transport. When the cells that form xylem die at maturity, the nucleus and cytoplasm disintegrate, leaving a
