Detailed explanation-1: -The stem is divided into nodes (points where leaves are or were attached) and internodes (the length of the stem between nodes). The leaves and stem together are called the shoot.

Detailed explanation-2: -In a plant, the point on the stem where leaves develop is called a node. The region between two adjacent nodes is called the internode.

Detailed explanation-3: -Nodes. A node is an area on a stem where buds are located (figure 6). It is a site of great cellular activity and growth. It is here that small buds develop into leaves, stems or flowers. When pruning, it is important to locate a plant’s nodes.

Detailed explanation-4: -leaf node (plural leaf nodes) (botany) One of the spots upon a stem where buds and intercalary meristems occur, usually marking the end of a season’s growth.

Detailed explanation-5: -Nodes on the stem mark the point from where the branches and the leaves emerge. While in some plants the nodes may help in vegetative propagation, the most important role of nodes is the leaf formation.
