30 maj 2022 · In the science of plant biology, a plant's stem consists of nodes and internodes. A plant stem's nodes are those critical areas from which leaves, branches, and aerial roots grow out from the stem, while the internodes are those intervals between the nodes.
Plant stems, whether above or below ground, are characterized by the presence of nodes and internodes (Figure \(\PageIndex{1}\)). Nodes are points of attachment for leaves. Leaves often consist of a thin region that attaches to the stem (the petiole ) and a broader blade (see Leaves ).

Nodes are the found in stems and serve as the point of origin of leaves, buds, and branching twigs. They are essential plant parts wherein biological processes, structural support and healing take place.
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
21 lis 2023 · Plant Node. A plant node represents a structure responsible for attaching the petiole to the stem. Nodes are often associated with stem locations where leaves and buds grow.
