This article is about the stem part of a plant. For the use of stem node in phylogenetics and cladistics, see Phylogenetic nomenclature. A stem is one of two main structural axes of a vascular plant, the other being the root. The stem is normally divided into nodes and internodes: 1  The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or inflorescences (flowers)). Adventitious roots may also be produced from the nodes.  The internodes distance one node from another.
