As we have learned, vascular plants can As we have learned, vascular plants can grow quite large thanks to their vascular grow quite large thanks to their vascular tissues. Vascular tissues transport tissues. Vascular tissues transport substances through the interior of the plant substances through the interior of the plant much like the circulatory system does in much like the circulatory system does in animals. animals. As water evaporates from the As water evaporates from the leaves of a plant, more water is drawn up by leaves of a plant, more water is drawn up by
