Micro-organisms ar very circumstantial one- stalled organisms and ar base over in the world. They atomic number 18 found in all brio things, plants and animals. There are more micro-organisms on and interior your frame than there are cellphones that make up your good body. Microorganisms fanny live in the air, on land, and in invigorated or salt water environments. Some of them, pathogens which sack be defamatory and causes diseases, but there are some microorganisms that are essential for living things to survive. (www.thinkquest.org) The four main categories of micro-organisms are bacteria, Fungi, virus and Protozoon. Bacteria cells are prokaryotic cells they do not name a membrane-bound nucleus but instead it lies inside the bacterial cytoplasm. This allows the designate of cellular information through the processes of translation, transcription and deoxyribonucleic acid reverberation this process all occurs within the same compartment and can interac t with other cytoplasmic structures. Bacteria have cell walls do of a peptidoglycan layer (consists of sugars and amino acids) that gives shape and makes the cell plastered forming a mesh like layer forthside(a)(p) the plasma membrane. It besides serves as an anchor for the Pili and Flagella; Pili are tiny hair-like structures that branch out from the cell wall. The structures have two purposes, they subjoin to tissues and cells giving them the great power to cause infection, also special Pili are used by bacteria for conjugation, a process in which one bacterium sends genes such as antibiotic protection to neighbouring bacteria cells. Flagella are long hair-like structures; flagella are used for travelling by the bacteria cell. Flagella help the bacteria move away from toxic chemicals or move toward nutrients. Bacterial reproduction near unremarkably occurs by cell division called binary fission. double star fission results in the formation of two bacterial cells that are genetically identical. Fungi unlike bac! teria cells are eukaryotes can follow as single-celled yeast but nearly commonly exist...If you want to get a full essay, high decree it on our website: BestEssayCheap.com
