Vascular plants (frae Laitin vasculum: duct), cried tracheophytes (frae the equivalent Greek term trachea) or heicher plants an aa, furm a lairge group o plants that are defined as those land plants that hae lignified tishies (the xylem) for conductin watter an minerals throughoot the plant. Thay forby hae a specialised non-lignified tishie (the phloem) tae conduct products o photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (includin conifers) an angiosperms (flouerin plants). Scienteefic names for the group include Tracheophyta^[5] an Tracheobionta.^[6]
