Question

Principles of microbiology essay

Answer 1

Explanation:

• Microbiology is the study of microorganisms. Microorganisms are those organisms that are less than a millimeter in size and require the help of a microscope to view them. Microorganisms can be unicellular or multicellular but have very simple cell structure, unlike the highly developed, complex organisms such as larger animals and humans. Microorganisms are classified based on criteria such as their cell structure, pattern of growth, nutrition, reproduction method, etc. However, microbial classification is a challenging task due to the dual nature of some microorganisms that exhibit both animal and plant like characteristics. Some microorganisms are photosynthetic like plants but they also have the ability to move from one location to the other using flagella and cilia like animals. Nevertheless, most microbiologists agree that organisms can be divided into bacteria, archaea and eukarya based on ribosomal RNA (rRNA) structure (Willey, Sherwood & Woolverton, 2009). Microbes reside within the human body in the form of normal flora that help in digestion. There are also other harmful microorganisms such as bacteria, fungi and viruses cause diseases in animals, humans and plants via food, water, air and direct contact.
