Key Concepts

Node

In the context of plant biology, a node refers to the specific point on a plant stem from which one or more leaves, branches, or aerial roots develop. Nodes are crucial for plant growth as they house axillary buds that can develop into new shoots, enabling the branching and overall structure of the plant.

Internode

The internode is the segment of the plant stem located between two successive nodes. It is primarily responsible for the elongation of the plant, contributing to the distance between leaves and overall stem height, and plays an important role in the spatial arrangement and growth dynamics of the plant.
