How mitosis is different from fission or budding?
Mitosis vs Binary Fission
The concept of cellular division is very tricky for some because there are many little things happening within the cell which are all of great importance to the entire cycle. However, different types of cell divisions like mitosis and binary fission have unique characteristics. They are easily confused with each other because both of them are asexual forms of reproduction as opposed to meiosis which is sexual in nature.
Mitosis is a type of cell division that takes place among non-sex cells (somatic cells). This type of cell replication is designed to increase the number of cells during the blastogenesis and embryogenesis of both animals and plants. The most distinct characteristic of the mitotic process is the production of two product cells (daughters) which are similar to each other as well as to their original cell (mother) in both quantitative and qualitative aspects.
Mitosis has four stages or phases namely: G1, S, G2 and the final mitotic phase which completes the cycle. The first to third stages comprise the so-called interphase. This phase, although there is no chromosomal division happening, is characterized by rapid cellular metabolic activity involving both the nucleus and cytoplasmic organs thus making it the longest collective stage. G1 is marked with RNA transcription and protein synthesis. S phase is evidenced by DNA synthesis. The G2 phase is primarily the acquisition of more cell energy and a further increase in cell size specifically the nucleolus.
Mitosis vs budding
Budding is a form of mitosis.
All cell divisions are nothing but mitosis except in gamates. Size of the cell during or after division does not matter. When the DNA is duplicated and evenly distributed, it would be called as mitosis.
