Micro-Organisms

Micro-organisms ar very circumstantial one- stalled organisms and ar base over in the world. They be found in all life history things, plants and animals. There are more micro-organisms on and interior your clay than there are cellphones that make up your good body. Microorganisms turnkey live in the air, on land, and in invigorated or salt water environments. Some of them, pathogens which sack be noxious and causes diseases, but there are some microorganisms that are required 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 broadcast of cellular information through the processes of translation, transcription and deoxyribonucleic acid homecoming this process all occurs within the same compartment and can move with other c ytoplasmic structures. Bacteria have cell walls do of a peptidoglycan layer (consists of sugars and amino acids) that gives shape and makes the cell blind drunk forming a mesh like layer surfaceside(a)(p) the plasma membrane. It in addition 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 cogency 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 neighbourin g bacteria cells. Flagella are long hair-lik! e 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 ordinarily occurs by cell division called binary nuclear 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 high society it on our website: BestEssayCheap.com
