The axillary buds begin developing when they are exposed to less auxin, for example if the plant naturally has weak apical dominance, if apical dominance is broken by removing the terminal bud, or if the terminal bud has grown far enough away for the auxin to have less of an effect. [2] Example of an axillary bud.
The roots are modified to have root hairs and branch indiscriminately with cells that take in water and nutrients, while the stems are modified to move water and nutrients to and from the leaves and flowers. [8] [9] [10] Stems have nodes with buds where leaves and flowers arise at
Node: A point of attachment of a leaf or a twig on the stem in seed plants. A node is a very small growth zone. Pedicel: Stems that serve as the stalk of an individual flower in an inflorescence or infrutescence. Peduncle: A stem that supports an inflorescence or a solitary flower. Prickle: A sharpened extension of the stem's outer layers, e.g ...
Adventitious buds develop from places other than a shoot apical meristem, which occurs at the tip of a stem, or on a shoot node, at the leaf axil, the bud being left there during primary growth. They may develop on roots or leaves, or on shoots as a new growth. Shoot apical meristems produce one or more axillary or lateral buds at each node.
The nodes are the eyes and each has a leaf scar. The nodes or eyes are arranged around the tuber in a spiral fashion beginning on the end opposite the attachment point to the stolon. The terminal bud is produced at the farthest point away from the stolon attachment and tubers, and thus show the same apical dominance as a normal stem.
In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots ...
Latent bud – an axillary bud whose development is inhibited, sometimes for many years, due to the influence of apical and other buds. Also known as a dormant bud. Leaf bud – a bud that produces a leafy shoot. Mixed – buds that have both embryonic flowers and leaves. Naked – Pseudoterminal – Reproductive – buds with embryonic flowers ...
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.
