Orchiopexy is performed in the event of testicular torsion, a urologic emergency presenting with intense pain and often without inciting injury. [citation needed]While neonatal torsion occurs with no anatomic defect to account for its occurrence (occurring in utero or shortly after birth), adult torsion results from a bilateral congenital anomaly often called a "bell-clapper deformity", where ...
Linnaeus referred to the description and picture of a plant in the Horti Malabarici as the plant for which the genus was created. [5] In 1753 he named this species as Ceropegia candelabrum. [6] Linnaeus did not explain the etymology but later explanations stated that the name Ceropegia was from the Greek [7] word keropegion κηροπηγɩον.
Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [ 1 ] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set.
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from either parent.
The set of rules and recommendations for formal botanical nomenclature, including plants, is governed by the International Code of Nomenclature for algae, fungi, and plants abbreviated as ICN. Plant description is a formal description of a newly discovered species, usually in the form of a scientific paper using ICN guidelines.
A plant morphologist makes comparisons between structures in many different plants of the same or different species. Making such comparisons between similar structures in different plants tackles the question of why the structures are similar. It is quite likely that similar underlying causes of genetics, physiology, or response to the ...
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare.
Amorphophallus species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species including Palpifer sexnotatus and Palpifer sordida. Pollinated flowers usually each develop into a globose berry, a fruit. The berries are red, orange-red, white, white and yellow, or blue, depending on the species.
