Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...
River morphology, the field of science dealing with changes of river platform; Urban morphology, study of the form, structure, formation and transformation of human settlements; Geomorphology, the study of landforms
Phytomorphology is the study of the physical form and external structure of plants. [1] This is usually considered distinct from plant anatomy, [1] which is the study of the internal structure of plants, especially at the microscopic level. [2]
Neurons can be morphologically characterized as unipolar, bipolar, or multipolar. Unipolar and pseudounipolar cells have only one process extending from the cell body. Bipolar cells have a two processes extending from the cell body and multipolar cells have three or more processes extending towards and away from the cell body.
The term "word" has no well-defined meaning. [7] Instead, two related terms are used in morphology: lexeme and word-form [definition needed]. Generally, a lexeme is a set of inflected word-forms that is often represented with the citation form in small capitals. [8] For instance, the lexeme eat contains the word-forms eat, eats, eaten, and ate.
The butterfly genus Heliconius contains some species that are extremely difficult to tell apart.. In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear.
In biology, polymorphism [1] is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).
Since the biological definition of male and female is based on gamete size, the evolution of anisogamy is viewed as the evolutionary origin of male and female sexes. [ 4 ] [ 5 ] Anisogamy is an outcome of both natural selection and sexual selection , [ 6 ] and led the sexes to different primary and secondary sex characteristics [ 7 ] including ...
