Internode

An internode is the area of ​​a plant stem between two adjacent nodes. Nodes on the stem form at the attachment points of leaves. Therefore, the internode is the part of the stem from one leaf to another.

The length of internodes can vary greatly among different plants and even in different parts of the same stem. In some plants, the internodes are very short and the leaves are arranged very densely (for example, in cereals). Others have long internodes and sparse leaves (for example, cacti).

The internode consists of parenchyma cells of the main tissue of the stem. These cells provide mechanical strength to the stem and conduct water and minerals from the root to the leaves. Inside the internode there are conductive bundles through which substances are transported.

Thus, the internode is an important functional part of the stem, providing communication between the leaves and the conduction of substances throughout the plant. The length and anatomical structure of the internodes are important for the growth and development of the plant.
