A STEM is one of the two main structural axes of a vascular plant, the other being the ROOT. The stem is normally divided in to nodes and inter-nodes.
NODES hold one or more leaves, as well as buds which can grow in to branches ( with leaves ,conifer cones, or inflorescence ( flowers )). Adventitious roots may also produced from the nodes.
INTER-NODES distance one node from another
