Bud, Small lateral or terminal protuberance on the stem of a vascular plant that may develop into a flower, leaf, or shoot. Buds arise from meristem tissue. In temperate climates, trees form resting buds that are resistant to frost in preparation for winter.

Jul 28, 2021 · A small swelling or protuberance on a stem or branch of a plant, containing the undeveloped shoot, leaf, or flower. A weaned calf on its first year, and whose horns are beginning to bud or form. Any small rounded part. Supplement In botany, buds may be classified according to function.
Identify the main parts of a leaf. Compare petiolate and sessile leaves. Distinguish among alternate, opposite, and whorled phyllotaxes. Compare simple, pinnately compound, and palmately compound leaves. Compare parallel, pinnate, and palmate venation in leaves. Recognize common leaf margins and shapes.
Definition of the Bud: The bud is a condensed rudimentary shoot. It is a compact body having an axis with a delicate growing point, nodes and very short unexpanded internodes and closely crowded young leaves (Fig. 47). The plumule is the first bud of the plant and the cabbage is a large bud.

A shoot or seedling originates from the plumule of the seed’s embryo and shares the following morphological features:
A shoot system of the plant body performs specific functions like: Protection: In some plants, a stem comprises hairy or spiny structures on its surface that harbour a plant from predators. Some plants like bracken produce toxic materialsthat also keep away the grazing animals. Support: The ground tissues like sclerenchyma and collenchyma also prov...
A shoot develops after embryogenesis, where a zygote inside an ovule goes through successive mitotic division to form a mature embryo. A mature embryo comprises five distinct regions that you could see in the diagram below: A top green part will produce seed leaves or cotyledons, in between which a shoot apical meristem is present. The shoot apex o...
In angiosperm anatomy, a leaf can be identified by where it emerges from the node. In a node, a leaf emerges below the axillary bud. Figure \(\PageIndex{1}\): A diagram of a node. Each node is comprised of a leaf (on the bottom) and an axillary bud (on the top, located in the axil where the petiole meets the stem).
