European beech (Fagus sylvatica) bud. In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem.Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately.
In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals. Internal budding or endodyogeny is a process of asexual reproduction, favored by parasites such as Toxoplasma gondii. It ...
The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots . Once formed, a bud may remain dormant for some time, or it may form a shoot immediately.
Bud; Crown (botany) Heteroblasty, an abrupt change in the growth pattern of some plants as they mature; Lateral shoot; Phyllotaxis, the arrangement of leaves along a plant stem; Seedling; Sterigma, the "woody peg" below the leaf of some conifers; Thorn (botany), true thorns, as distinct from spines or prickles, are short shoots
1. Referring to the arrangement of floral or foliar organs in a bud when each organ or segment has one edge overlapping the adjacent organ or segment; a form of imbricate arrangement. See contort. 2. (of leaves) A type of vernation in which one leaf is rolled up inside another. 3.
Accessory bud – an embryonic shoot occurring above or to the side of an axillary bud; also known as supernumerary bud. Adventitious bud – a bud that arises at a point on the plant other than at the stem apex or a leaf axil. Axillary – an embryonic shoot which lies at the junction of the stem and petiole of a plant. Dormant – see "Latent ...
In botany, a sport or bud sport, traditionally called lusus, [2] is a part of a plant that shows morphological differences from the rest of the plant. Sports may differ by foliage shape or color, flowers , fruit, or branch structure.
The limb bud is a structure formed early in vertebrate limb development. As a result of interactions between the ectoderm and underlying mesoderm, formation occurs roughly around the fourth week of development. [1] In the development of the human embryo, the upper limb bud appears in the third week and the lower limb bud appears four days later ...
