Fission (biology) - Wikipedia
The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. [1] [2] [3] The fission may be binary fission, in which a single organism produces two parts, or multiple fission, in which a single entity produces multiple parts.
分裂 (生物学) - 维基百科，自由的百科全书
分裂 （英語： Fission），又叫 裂殖，在 生物学 中是指一个细胞（或身体、种群或物种）分为两个或多个部分，以及这些部分再生为细胞（身体、种群或物种）。 通常是 單細胞生物 所形的生殖方式。 該種生物直接行細胞分裂後就可產生兩個（或更多）新個體。 例如： 草履蟲 、 變形蟲 以及多數的 細菌 等。 [ 1 ][ 2 ][ 3 ] 二分裂 （英語： Binary fission）产生两个细胞、种群或物种等，而 複分裂 （英語： multiple fission）产生多于两个的细胞、种群或物种等。 ^ Carlson, B. …
Mitochondrial fusion and fission in cell life and death
2010年11月23日 · The antagonistic and balanced activities of the fusion and fission machineries shape the mitochondrial compartment, and the dynamic behaviour of mitochondria allows the cell to respond to its...
Fusion and Fission - Cell Press
2002年3月22日 · Recent studies have revealed that membrane insertion for furrowing and scission of the residual bridge is a key aspect of animal cytokinesis. Cytokinesis creates membranous barriers between the daughter cells to complete the cell cycle.
Fission - (Cell Biology) - Vocab, Definition, Explanations - Fiveable
Fission is the process by which a single entity divides into two or more separate entities, commonly seen in the context of cellular biology and vesicle dynamics. In cell biology, fission plays a critical role in the formation and movement of vesicles, which are membrane-bound compartments that transport materials within the cell.
Increasing Diversity of Biological Membrane Fission Mechanisms - Cell …
2018年1月4日 · In this review, we propose an updated overview of fission mechanisms, and try to extract essential requirements for each. We also present examples of cellular processes that involve these fission mechanisms. Finally, we list pending questions, whether they are specific to a peculiar fission mechanism or more general to the field.
How membrane fusion and fission occur in live cells
2023年6月13日 · Merging and division of cell membranes, known as fusion and fission, are vital to numerous processes in eukaryotic cells, like those of humans, animals, and plants. However, the ways that membranes’ two thin layers, known individually as ‘leaflets’, remodel themselves to control fusion and fission remains unclear due to difficulties of ...

细胞分裂 （英語： cell division）是生物体 生长 和 繁殖 的基础，通常由一个 母细胞 产生两个或若干 子细胞，是 細胞週期 的一部分。 产生两个不同子细胞的分裂被称为 不对称细胞分裂，也称为异裂。 [1] 根据类型常可区分为 有丝分裂 （mitosis）和 无丝分裂，在真核生物中以有丝分裂尤为重要，它不改变 染色体 的倍数。 [2] 细胞 分裂的另外一种形式是 减数分裂 （meiosis）。 减数分裂产生染色体倍数减半的 生殖细胞，即 配子，这是 有性生殖 的必要条件。 [2] 如果细胞分裂失 …
Organelle fission in eukaryotes - ScienceDirect
2001年12月1日 · Consistent with their endosymbiotic origins, mitochondria in protists and chloroplasts in photosynthetic eukaryotes have evolved organelle-targeted forms of FtsZ, the prokaryotic ancestor of tubulin, as key components of their fission complexes.
