WebThe two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant. Most extant plants on Earth have vascular systems, including the lower vascular plants ( lycophytes and ferns ), gymnosperms, and angiosperms. WebThe adaptations and characteristics which ARE present in (nearly) all land plants include: A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light.
