Features of kingdom prokaryotae
The Kingdom Prokaryotae, also known as the domain Bacteria, is a diverse group of single-celled microorganisms that are distinguished by their small size, simple cellular structure, and rapid rate of reproduction. There are two main groups within the Kingdom Prokaryotae: the Eubacteria and the Archaebacteria. Both groups are characterized by their lack of a nucleus and other membrane-bound organelles, and instead have their genetic material organized within a single circular chromosome located in the cytoplasm.
One of the most notable features of prokaryotes is their small size. Most prokaryotes are only a few micrometers in length, making them invisible to the naked eye. This small size allows them to inhabit a wide range of environments, including soil, water, and even inside the human body.
Prokaryotes are also characterized by their simple cellular structure. In contrast to eukaryotes, which have complex cell structures with multiple membrane-bound organelles, prokaryotes have a more streamlined cell structure. They lack a nucleus and other membrane-bound organelles, and instead have their genetic material organized within a single circular chromosome located in the cytoplasm.
Prokaryotes are also known for their rapid rate of reproduction. They have a short generation time and can reproduce through a process called binary fission, in which a single cell divides into two daughter cells. This allows prokaryotes to rapidly colonize new environments and adapt to changing conditions.
Prokaryotes are also highly adaptable and can survive in a wide range of environments. They are found in almost every habitat on Earth, including extreme environments such as hot springs and polar ice caps. They are also capable of using a variety of energy sources, including sunlight, organic matter, and inorganic compounds.
In conclusion, the Kingdom Prokaryotae is a diverse group of single-celled microorganisms characterized by their small size, simple cellular structure, and rapid rate of reproduction. Their adaptability and ability to survive in a wide range of environments make them an important component of the Earth's ecosystems.
Therefore, they exhibit selective toxicity. Bacteria and cyanobacteria play following role in biological nitrogen fixation: I. For instance, disease-causing bacteria have played a significant role in human history, causing diseases such as tuberculosis, gonorrhea, plague, whooping cough, pneumonia, syphilis, and botulism. Silage is used as fodder. They selectivity extract metals from raw ore.
👑 Kingdoms: Prokaryotae, Protoctista, Plantae, Fungi, Animalia
It is a facultative anaerobe and also a parasite of mammals actually responsible for the skin infection streptothricosis.

Industrial role of bacteria and cyanobacteria Prokaryotes play important role in industry. Bacterial biofilms are often made up of Should these instances of prokaryotic sociality prove to be the rule rather than the exception, it would have serious implications for the way we view prokaryotes in general, and the way we deal with them in medicine. They also possess extrachromosomal DNA known as plasmids. It is quite pertinent to state at this juncture, that the actinomycetes do possess and exert an appreciable practical impact by virtue of the fact that they invariably play an apparent major role in the following two highly specialized and particular aspects, namely: a Mineralization of organic matter in the soil, and b Primary source of most naturally synthesized antibiotics. They can be free-living or parasites.
These bacteria live in nodules. Dry heat causes the oxidation of chemical compounds of the microbes and kills them. Although the exact classification of cyanobacteria is still under debate, some scientists now classify cyanobacteria in the Kingdom Prokaryotae, while algae remains classified in the Kingdom Protista. Archaebacteria consist of a small group of primitive anaerobes organisms that do not require oxygen. The important chemical agents used for disinfection are oxidizing and reducing agents. General Characteristics The general characteristics of the actinomycetes are as stated under : a The branching network of hyphae usually developed by the actinomycetes, grows critically both on the surface of the solid substratum e. Scientists distinguish prokaryotes from eukaryotes, which are more complex organisms with cells that contain a nucleus, such as plants and animals.
Economic importance of prokaryotes and its roles
The small size of prokaryotes allows ions and organic molecules that enter them to quickly diffuse to other parts of the cell. DNA- It is the genetic material of the cell. Microbial Phylogeny and Evolution: Concepts and Controversies. You will study plant biology including photosynthesis, diseases such as fungi and worms, and plant hormones. Classification The actinomycetes have been duly classified into three major divisions based upon the follow-ing characteristic features: a Whole cell carbohydrate patterns of aerobic actinomycetes b Major constituents of cell wall types of actinomycetes, and c Groups of actinomycetes based on whole cell carbohydrate pattern and cell wall type.

General Characteristics of Prokaryotes
So they are used for manufacturing butter, yogurt, cheese, cakes and bear. This ability is used in waste processing and bioremediation. These filaments are made up of two types of cells Green photosynthetic cells fix the atmospheric carbon dioxide and release oxygen during photosynthesis. For example Nostoc lives in the mucilage cavities of Anthoccros and fixes atmospheric nitrogen. In contrast, eukaryotic organisms have their genetic material compartmentalized inside a specialized membrane.
Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Provided by: OpenStax CNX. The feature that most distinguishes the bacteria and blue-green algal members of the Prokaryote from the members of the other kingdoms is the lack of membrane-bound structure around the genetic material. In 1990 American microbiologist Carl Woese proposed that bacteria be divided into two groups, archaebacteria and bacteria, based on their structural and physiological differences.

Kingdom monera characteristics
The characteristics of the prokaryotic cells are mentioned below. For example halogens chlorine , phenols, hydrogen peroxide, potassium per magnate, alcohol and formaldehyde etc. Area of the cytoplasm that contains the prokaryote's single DNA molecule. Treatment of bacterial diseases Bacterial infections are treated with antibiotics. However, the entire phenomenon of N 2 fixation is quite similar to that of Rhizobium wherein it is both O 2 sensitive and essentially and predominantly needs two elements, namely : molybdenum Mo , and cobalt Co. For example, the antibiotics chloramphenicol and tetracyclin inhibit the bacterial ribosome. Prokaryotae Prokaryote is a kingdom, or division, in the classification scheme devised for all life on bacteria and blue- Besides the kingdom Prokaryotae, there are the Protista eukaryotic organisms' organisms that have a nucleus enclosed in a well-defined membrane , Fungi , Animalia eukaryotes organized into complex organisms , and Plantae.

Archaebacteria are a very diverse group of bacteria and have several features that set them apart from the other Prokaryotae. Thes… Protista , The Kingdom Protista is the most diverse of all six kingdoms. Chlamydia, another phylum of obligate intracellular parasites, contains species that can cause pneumonia, or urinary tract infection. Actinomycetes Based on Whole Cell Carbohydrate Pattern and Cell Wall Type One may observe from Table 3. Besides, a larger segment of these spores are specifically devoid of any thermal resistance; however, they do withstand dessication quite satisfactorily, and thus exhibit considerable adaptive value. Some of these are: 1.
Five Kingdom System of Classification
On the origin of eukaryotes". Components of Prokaryotic Cells The prokaryotic cells have four main components: Plasma Membrane-Â It is an outer protective covering of phospholipid molecules which separates the cell from the surrounding environment. They degrade the industrial and domestic wastes. By the end of the course, you will have increased your knowledge set, learned something really interesting, and possibly kickstarted a great career. The sexual mode of reproduction involves conjugation. This association is called lichens. Then the scientists can determine the function of genes, enzymes and metabolic pathways in bacteria.
Distinguishing features of Kingdom Prokaryotae?
They cause disease mainly in people suffering from immunosuppression or cystic fibrosis. But they do not affect the structurally-different eukaryotic ribosome. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae.
