Nonvascular Plants: Nonvascular plants belong to the division Bryophyta, which
includes mosses, liverworts, and hornworts. These plants have no vascular tissue, so the
plants cannot retain water or deliver it to other parts of the plant body.
Vascular Plants: Vascular plants have a specialized conducting system consisting
mostly of phloem (food-conducting tissue) and xylem (water-conducting tissue),
collectively called vascular tissue.
