When this tissue grows centripetally, it is known as exarchy.
"Air-seeding" causes cavitation in this tissue, which can be fixed by importing solutes through ray cells. Mesarch development of this tissue is found in many pteridophytes. When this tissue grows centripetally, it is known as exarchy. The secondary type of this tissue grows(*) inward from the vascular cambium. This tissue includes both more primitive tapered cells called tracheids, and the shorter, wider vessel elements. For 10 points, name this kind of vascular plant tissue that uses root pressure and transpirational pull to transport water, unlike phloem.
