Micro-organisms ar very circumstantial one- stalled organisms and ar base everywhere in the world. They are found in all living(a) things, plants and animals. There are more micro-organisms on and interior your eubstance than there are cellphones that make up your good body. Microorganisms piece of tail live in the air, on land, and in invigorated or salt water environments. Some of them, pathogens which sack be catastrophic and causes diseases, but there are some microorganisms that are take for living things to survive. (www.thinkquest.org) The four main categories of micro-organisms are bacterium, 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 conduct of cellular information through the processes of translation, transcription and deoxyribonucleic acid sideboard this process all occurs within the same compartment and can mov e with other cytoplasmic structures. Bacteria have cell walls make of a peptidoglycan layer (consists of sugars and amino acids) that gives shape and makes the cell austere forming a mesh like layer prohibitedside(a)(p) the plasma membrane. It similarly 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 dexterity to cause infection, also special Pili are used by bacteria for conjugation, a process in which one bacteria sends genes such as antibiotic protection to neighbouring bacteria cells. Flagella are long hair-like structure! s; 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 normally occurs by cell division called binary fission. double star fission results in the formation of two bacterial cells that are genetically identical. Fungi unlike bacteria cells are eukaryotes can experience as single-celled yeast but nearly commonly exist...If you want to get a full essay, high hostelry it on our website: BestEssayCheap.com
