Following the covid eruption, you may have come across the terms disinfection, sterilization, and even sanitisation at regular intervals. All of these phrases refer to antimicrobial procedures aimed at eradicating pathogenic microorganisms and other infectious agents. Disinfection is a common and simple method of decontamination that we employ on a daily basis. On the other hand, sterilization is predominantly linked with medical, industrial, and scientific areas and is not performed very … [Read more...]
Difference Between Lytic and Lysogenic Phase
The main difference between the two life cycles followed by the phage during the infection to the bacterium is that in the lytic phase the phage infects the machinery of the cell to make more of its components, and later they lyse, or destroy, the cell, and releases new phage particles. However, in the lysogenic phase, the phage does not destroy the host cell; instead, they insert their genetic material with the chromosome of the host cell, which replicates it as a unit. Bacteriophage or … [Read more...]
Difference Between Binary Fission and Budding
Binary fission is seen in algae and in few protozoans where there is the division of the nucleus of the cell in the cyst (protective covering), and further, the cyst breaks, and two new offsprings are released. Budding is another kind of asexual reproduction, where a bulb-like projection occurs from the parent body called the bud, which gets detached and forms a new individual. This is seen in Hydra. Reproduction is the process, through which living organisms can produce new ones of their … [Read more...]
Difference Between Binary and Multiple Fission
Both types of fission are the types of asexual reproduction, in which the binary fission give rise to two daughter cell from the parent cell, whereas in multiple fission, the parent cell gives rise to numerous daughter cell. Binary fission is one of the most common methods of reproduction in the prokaryotes, while multiple fission occurs in some parasitic species and protists. Generally, in biology, one of the basic of the critical concepts is 'reproduction'. It gives the knowledge of how the … [Read more...]
Difference Between Neutrophils, Eosinophils and Basiophils
The neutrophils are one that reaches the site of the infection quickly when the immune response triggers, and thus helps in fighting against the foreign particles by ingesting them. Eosinophils are another type of white blood cells, that fight against infection, allergies and diseases. Basophils are always present against allergens and prevent blood clotting in the body, as it contains heparin which is the natural blood thinner. White blood cells are produced by the body naturally, which are … [Read more...]
Difference Between Endotoxin and Exotoxin
Endotoxins are the Lipopolysaccharide-protein complexes (LPS), responsible for making an integral part of the cell wall of Gram-Negative Bacteria and are released at the time of cell death or lysis of bacteria. Exotoxins are the proteins which are secreted by few species of bacteria and get diffuse into the nearby or surrounding medium. Secondly, endotoxins are heat stable, weakly immunogenic while exotoxins are heat labile, highly antigenic. Endotoxins are produced by Gram-negative bacteria, … [Read more...]
Difference Between Bacteria and Virus
Bacteria are said to occupy the large domain of the prokaryotic cell, while the virus is known as minor infection causing agent. Secondly, bacteria reproduce by themselves through asexual method whereas virus needs a host cell to replicate as they lack cellular machinery but consist of DNA and RNA. When people fall ill, the first thing that struck to their mind is about any contamination, related to bacteria, fungi or virus. This routine is typical in all age of peoples, as these terms like … [Read more...]
Difference Between Bacteria and Fungi
Bacteria and Fungi come under different categories; the former one is the prokaryotic cell while the latter one is Eukaryotic cells. Apart from this, there are many differences between them like bacteria need a host to live, and they can be autotrophs as well as heterotrophs, whereas fungi grow their own and are heterotrophs which depend on others for their food. Bacteria do not have nuclear membrane enclosing nucleus, while Fungi (eukaryotes) have well- defined nucleus surrounded by the nuclear … [Read more...]
Difference Between Moist Heat and Dry Heat Sterilization
When the process of sterilization is carried out at high -pressure through water (steam) it is called as moist heat sterilization, on the other hand, dry heat sterilization is carried out at high temperature under dry condition. The best way to kill microbes is through 'heat', as it destroys their proteins as well the enzymes present in them. So sterilization (destroying or killing the microbes) process follows this principle of killing microbes, which can be either by giving wet (moist) heat … [Read more...]
Difference Between Archaea and Bacteria
Despite being in the same category of prokaryotes, archaea and bacteria show variances in their genetic makeup, as the metabolic pathways, and other enzymes, genes possessed by the archaea closely resembles eukaryotes rather bacteria. Simple, microscopic, ambiguous microorganisms mark their presence universally, whether its deep in water, high temperature, soil or any extreme conditions. The evolving history of these cells is considered to be old as more than 3.5 billion years ago. Archaea … [Read more...]
