Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself is produced by fusion of two gametes, each having been produced by meiotic cell division. [5] [6] After growth from the zygote to the adult, cell division by mitosis allows for continual construction and repair of the organism. [7]

Mitosis is generally preceded by the S phase of interphase, when the cell's DNA is replicated, and either occurs simultaneously with or is followed by cytokinesis, when the cytoplasm and plasma membrane are divided into two new daughter cells. Colloquially, the term "mitosis" is often used to refer to the entire process of cell division, not ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Cell division generally occurs by a complex, carefully structured sequence of events involving the reorganization of the parent cell's internal contents, the physical cleaving of the cytoplasm and plasma membrane, and the even distribution of contents between the two resulting cells, so that each ultimately contains approximately half of the ...
In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. [149] The area of skin involved can vary from small to the entire body. [149] [150] Diagnosis – Medical diagnosis (abbreviated Dx [151] or D S) is the process of determining which disease or condition explains a person's symptoms ...
The sixth edition of the previous standard, Nomina Anatomica, was released in 1989.The first edition of Terminologia Anatomica, superseding Nomina Anatomica, was developed by the Federative Committee on Anatomical Terminology (FCAT) and the International Federation of Associations of Anatomists (IFAA) and released in 1998.
