The Apicomplexa display remarkable variation in offspring number, whether karyokinesis follows each S/M-phase or not, and whether daughter cells bud in the cytoplasm or bud from the cortex. The horizon on cell division variants is expanded here by advancing insights on the fascinating cell division modes found in the Apicomplexa, a key group of protozoan parasites. The key difference between mitosis and binary fission is that the latter takes place among prokaryotes (cells with no nucleus) while mitosis takes place among eukaryotes (cells with a nucleus present).īinary fission is a faster method of cellular division unlike mitosis whose process is lengthy and detailed.īinary fission doesn’t have the elaborate four stages (G1 to final mitotic phase) that are witnessed in mitosis.Cellular reproduction defines life, yet our textbook-level understanding of cell division is limited to a small number of model organisms centered around humans. Longitudinal binary fission happens in the euglena when the plane resembles the longitudinal alignment. On the other hand, transverse binary fission occurs between paramecium and planaria in cases wherein cytoplasmic division plane resembles the specimen’s traverse axis. Simple binary fission takes place in amoebas. Here, there is no participation of the nuclear envelope and centromeres.īinary fission is categorized into three types that are simple, transverse and longitudinal. Unlike mitosis that has several stages in its cycle, binary fission, on the other hand, is brief and completes quickly. Binary Fissionīinary fission is also referred to as prokaryotic fission and is known as the most popular and easy method of asexual reproduction. For the G2 phase, cells typically receive more energy and grow in size particularly the nucleolus. RNA transcription is associated with G1 while DNA synthesis signifies the S phase. A lot of activity is centered on the nucleus and cytoplasmic organs making this stage lengthy. However, it’s important to mention that no chromosomal division takes place at this stage. Inter-phase happens during the first three stages where cellular metabolic activity is at its peak. There are four main stages that are associated with mitosis namely G1, S, G2 and the last phase that ends the cycle. The most distinct observation of the mitotic process is the production of two daughters that are identical with the same case applying to the original cell (in this case their mother). This is a replication process that leads to more cells during the formation and development of the embryo in animals and plants. When a cell division takes place between somatic cells (non-sex cells), this process is referred to as mitosis. Many people tend to confuse binary fission and mitosis since both of them are a sexual form of reproduction. All these processes have their own peculiar characteristics and, therefore, differ from each other in terms of how they take place. It is essential to mention that cell division consists of key processes such as mitosis and binary fission. As tiny as it is, there are many processes that take place within a cell and contribute largely to the completion of an entire cycle. Many people get confused particularly when it comes to having a clear understanding of how cellular division takes place.
