Final answer:
Leaves are connected to plant stems at nodes, with axillary buds located at each node having the potential to grow into new stems or branches.
Step-by-step explanation:
Leaves are attached to stems at nodes and have lateral axillary buds that can develop into new stems or branches. Nodes are the points where leaves, aerial roots, or flowers are connected to the plant stem. An internode is the stem region between two nodes. The stalk that extends from the stem to the base of the leaf is called the petiole. The axillary bud is typically found in the axil, which is the area between the base of a leaf and the stem, and it has the potential to grow into a new branch or a flower.
