Final answer:
The stem regions at which leaves are attached are called nodes. Internodes are the regions between two nodes. Axillary buds are found in the axil, which have the potential to give rise to branches or flowers.
Step-by-step explanation:
The stem regions at which leaves are attached are called nodes. Nodes are the points of attachment for leaves, aerial roots, and flowers. An internode is the stem region between two nodes.
For example, if you look at Figure 30.4 or Figure 23.4, you can see that the leaves are attached to the stem at specific points called nodes. The stem region between two nodes is referred to as an internode.
Additionally, the area between the base of a leaf and the stem is called the axil, where an axillary bud is usually found. Axillary buds have the potential to give rise to branches or flowers.
