Vine is a kind of climbing plant of woody or herbaceous, which roots in soil and is easy to bend or soft. The stem is slender and cannot stand upright. It has the climbing habit of climbing other things upward by its own function or special structure. When there is no other thing to climb, it grows by crawling or hanging.
The common point of vines is that their stems are slender and cannot stand upright, but they all have the climbing habit of climbing upward by their own function or special structure.
