Adorable crumbs - germs and bacteria - can kill a much larger and more developed living thing. But it is this "trifle" that is a necessary condition for a number of processes, without which life on Earth would be impossible.
Definition
Microbes, or microorganisms, is a huge group of living organisms, the size of which does not exceed 0.1 mm.
Bacteria is a domain of non-nuclear microorganisms united in the super kingdom of Prokaryotes.
Comparison
Microbes are really tiny. This odious non-systematic group includes organisms whose size does not exceed 0.1 mm. Moreover, the group can contain both nuclear and non-nuclear creatures.
Bacteria are the first organisms that appeared on Earth and became the most widespread, having mastered the soil, water, air. There are also species that live in other organisms or in the middle of larger microbes.
Bacteria is the super kingdom of the Prokaryotes, which contains about 22 types of different organisms. Their sizes vary in the range of 0.5-5 microns. In this case, bacteria can be multicellular and unicellular creatures.
The size of the bacteria is limited by the cellular porous wall, through which the desired molecules enter the cell. The cell contains functional organelles, as well as nucleoids not surrounded by a membrane, and plasmids in which genetic information is concentrated. The content of microbes depends on the taxon to which they belong.
Bacteria move with the help of flagella or villi. These organisms produce vital energy through photosynthesis, fermentation or respiration. Bacteria multiply in all known ways, from primitive division and budding to the more advanced sexual method.
There are pathogenic bacteria that cause diseases, and some types of these organisms make it possible to obtain products such as cheese, yogurt, kefir, and sauerkraut. Some bacteria found in the human intestine help it digest food, while other organisms are the basis for the creation of bacteriological weapons.
Conclusions TheDifference.ru
- Bacteria are a taxon united by the principle of non-nuclearity, and microorganisms are a group that contains all creatures smaller than 0.1 mm.
- Microbes are larger than bacteria.
- The concept of "microorganisms" is more comprehensive than "bacteria".
