What are bacteria? Bacteria are very different from viruses. First of all‚ bacteria are much larger in size. The largest virus is only as big as the very smallest bacterium (singular for bacteria). But bacteria are still microscopic and cannot be seen with the naked eye. They are so small that the sizes of bacteria are measured in micrometers (10‚000 micrometers = 1 centimeter). By comparison‚ the head of a pin is about 1000 micrometers wide. Though more complex than a virus‚ the structure of a

P1: you must explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. P2: you must explain how pathogenic microorganisms grow and spread. In this assignment I am going to explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. I will then explain how pathogenic microorganisms grow and spread. Infection is the process where germs enter a susceptible area in the body‚ where they multiply‚ resulting in disease. Colonisation is where microbes are present

The difference between bacteria‚ viruses‚ fungi and parasites are: Bacteria are single celled organisms that can rapidly multiple themselves every 10 minutes up to 10 times each bacterial cell‚ but they do not live or reproduce in a human cell. When threatened they will make a copy of their DNA to enable them to come back to life in the right conditions. They are able to survive in most extreme living conditions including with and without oxygen‚ there are various types of bacteria such as Cocci/Coccus

Bacteria and viruses are tiny microscopic pathogens that can cause infectious disease‚ or even result in death. “Infectious diseases remain a major cause of death‚ disability‚ social‚ and economic disorders for millions of people around the world.

differentiate between bacteria‚ fungi and yeast‚ we plant four different microbes in plates under the same environment for one week and compare the growth of the four microbes by macroscopic and microscopic observation. Meanwhile‚ the diversity of bacteria and fungi in humans‚ the environment and wood could be observed. In addition‚ the four substrates are cultured in two media‚ MEA and NA‚ under the same condition. Thus‚ how nutrients affect the growth of bacteria and fungi could be achieved. During

A fungus (/ˈfʌŋɡəs/; plural: fungi[3] or funguses[4]) is a member of a large group of eukaryoticorganisms that includes microorganisms such as yeasts and molds (British English: moulds)‚ as well as the more familiar mushrooms. These organisms are classified as a kingdom‚ Fungi‚ which is separate from plants‚ animals‚ protists and bacteria. One major difference is that fungal cells have cell walls that contain chitin‚ unlike the cell walls of plants and some protists‚ which contain cellulose‚ and

a living thing? Are viruses alive or not? To figure out this question we first have to know‚ what defines a living thing. According to the online Merriam-Webster Dictionary‚ life is in particular “an organismic state characterized by capacity for metabolism‚ growth‚ reaction to stimuli‚ and reproduction.” For about 100 years‚ scientists have repeatedly changed their mind over what viruses are. First seen as poisons‚ then as life-forms‚ then biological chemicals‚ viruses today are thought of as

a good report on fungus - The kingdom of Fungi contains single-celled and multicellular organisms that absorb nutrients for food. Fungi‚ together with bacteria decay and decompose organic matter. Some fungi can be parasitic and cause serious diseases in plants and animals. Though considered an individual kingdom today‚ traditionally fungi were classified as plants with no stems‚ leaves‚ or chlorophyll. About 100‚000 species of fungi are known. Most fungi are made of protoplasm-containing tubes called

NATURE AND DEVELOPMENT OF VIRUSES The Nature of Viruses Viruses are sub-cellular agents of infection that must utilize the cellular machinery of bacteria‚ plants or animals in order to reproduce. Composed of a single strand of genetic material (DNA or RNA) encased in a protein capsid‚ a virus is too small to be seen by standard light microscopy; indeed‚ most are less than one hundredth the size of a bacterium. Specific proteins on the viral capsid attach to receptors on the host cell; this

They provide fundamental products including foods‚ medicines‚ and enzymes important to industry. They are also the unsung heroes of nearly all terrestrial ecosystems‚ hidden from view but inseparable from the processes that sustain life on the planet.
