Node refers to the place from which a leaf emerges. "Internode" is the term for the area between any two adjacent nodes.
The stem contains two structural components called nodes and internodes. One of the two structural components of a vascular plant is the stem. Axillary buds on nodes can grow into branches, flowers, or cones, while internodes are in charge of the stem's extension.
The following table lists some of the key differences between nodes and internodes along with basis of differentiation:
Basis |
Nodes |
internodes |
Meaning |
Node refers to the leaf's point of attachment. |
The internode is the area between the two nodes. |
Identification |
This area can be recognized by the presence of scars, buds, leaves, or branches. |
absence of any remnants, such as buds, leaves, or branches, or any scars. |
Cellular activity |
Nodes are areas that experience rapid cellular growth and activity. |
The length of the plant is increased by the internode's activity, which maximizes the space between the nodes. |
Axillary bud |
An axillary bud is present. |
Contains no axillary bud. |
Function |
bear buds, which may grow into cones, flowers, or branches. |
responsible for extending the stem's length. |
A node is a structural component of a vascular plant's stem that creates a small swelling in the stem. Nodes have generative structures like axillary buds, flower buds, or cone buds as well as scars. The axillary buds are in charge of branch development. Some plant nodes also produce aerial roots.
The area of the stem between two nodes that follow one another is known as the internode. The internode's length creates the necessary separation between the two following nodes. However, some plants, like dwarf conifers, have internodes that are always short. These plants can therefore be pruned or sheared into various shapes.
Following are some similarities that can be found between nodes and internodes:
A node is a small growth on a vascular plant's stem that is distinguished by the presence of an axillary bud or scar that will eventually become a branch. Nodes may also contain flower or cone buds in addition to axillary buds. The portion of the stem between two adjacent nodes is known as an internode. It is in charge of making the plant grow taller. Therefore, structure and function are what distinguish a node from an internode.
