growing vine shoot in Portugal's Alentejo. The grapevine is a freeloader, and
energy and time growing a self-supporting trunk, it hitches a ride on trees in its native habitat, and trellis
systems in vineyards. A vitaltool for this growth habit is the tendril, which upon contact will grasp hold of
it - a response termed thigmotropism. Of course, vines can (and do) grow unsupported (termed bush vines).
