Binary Fission Pros and Cons List

4 stars based on 78 reviews

Binary fission is a simple mode of asexual reproduction exhibited by prokaryotes and unicellular organisms. It results in the formation of two identical daughter cells, each a replica of the parent cell. Though mitosis and meiosis may seem similar to binary fission, they are all very different types of cell division. The former two are observed in higher and more developed organisms. Such processes have distinctive steps involving nucleus and centromeres, which are absent in prokaryotic cells.

Steps of Binary Fission. It is to be borne in mind that chromosome in prokaryotes comprises only a single circular DNA. Like other cellular processes, binary fission occurs when organisms are thriving in favorable environmental conditions. The step-by-step process of binary fission is enlisted below:. Replication of deoxyribonucleic acid DNA marks the initiation of the binary fission process.

The process of replicating nucleic acid begins from a replication origin. Following this, a replication bubble is formed, which separates the DNA strands. Each of the strands then serve as a template for synthesis of the complementary strand. Then, the DNA or genetic material is duplicated. The second step in binary fission is growth of the parental cell. After duplication of DNA, the parent cell is ready to reproduce by binary fission process. As a preparatory step, it grows considerably and increases its size.

At the same time, the two circular DNA strands migrate and attach themselves to plasma membrane in different sites. Following sufficient growth, the cell elongates and starts pulling apart from opposite poles. A division septum is created transversely in the cell. In short, the cell membrane extends and pinches inwards. During this process, separation of the two chromosomes takes place. This step is controlled by a group of proteins that assemble near the division site.

Inward growth of the cell membrane is associated with development of a new cell wall. The final binary fission step is splitting of the parental cell into two daughter cells, each having a nuclear material chromosome of its own.

Problems may occur in any of the steps in binary fission, resulting in abnormalities in the daughter cells. Some simple organisms, like Chlamydiae and Paramecia reproduce by both sexual and asexual means, depending upon the prevailing conditions. Thus, they have an advantage over simpler unicellular organisms in terms of generating more daughter cells and increasing their population. After binary fission is over, the outcome is two genetically identical daughter cells. Under favorable environmental conditions, each of these cells grow and develop into matured cells.

Speaking about binary fission examples, you can go through organisms that reproduce asexually.

A type of reproduction, in which fertilization and other processes like ploidy reduction, meiosis, etc. This form of reproduction doesn't require a partner; which means that only a single parent is involved in the process.

A more technical definition of asexual reproduction would be the regeneration, which takes place as a result of fusion of gametes. The single-celled organisms, which reproduce asexually are protists, bacteria, and archaea.

The different modes, through which asexual reproduction takes place are binary fission, spore formation, vegetative reproduction, and budding. The budding process results into the formation of daughter cells from mother cells. This mode of reproduction is observed in unicellular as well as multicellular organisms. Binary fission is the simple process, in which a single cell divide into two, and the process continues. Higher Number of Offspring. In asexual reproduction, a higher number of offspring are produced.

The advantage of having offspring in greater number is that their survival rate increases greatly. Production of spores is highly effective from the point of dissemination. The spores being lightweight are carried to long distances by the means of wind and water. Even animals carry out dispersal of spores that are attached to their bodies. A Partner is Not Required. For asexual reproduction to take place, there is no need of a partner. It is a faster and easier form of reproduction.

The energy spent by organisms in finding a partner during sexual reproduction is saved in this mode. The individuals produced as a result of asexual reproduction have the same DNA.

It means that the daughter cells produced as a result of asexual reproduction are clones. Cloning would thus prove to be beneficial in such cases. One of the advantages of asexual reproduction is the production of breeding stock.

The breeding stock obtained from asexual reproduction is used for the propagation of species in the future. The process is more or less like cloning. The asexual form of reproduction leads to prolific multiplication of organisms.

However, the vigor or genetic diversity required for a species to survive in the long term is found lacking in such organisms. Asexual Reproduction in Plants. Asexual Reproduction in Animals.
