RE: Microbes Are Everywhere: You Can Run but You Can Not Hide
Microorganisms or microbes are organisms that are very small (usually less than 1 mm) so that to observe it requires a relief tool. Microorganisms are often single-celled (unicellular) although some single-celled protists are still visible to the naked eye and there are some multicellular species invisible to the naked eye. The study of microorganisms is called microbiology.
Microorganisms are usually considered to include all prokaryotes, protists and micro algae. Fungi, especially small ones and do not form hyphae, can also be considered as part of it even though many do not agree on it. Most people assume that what can be considered microorganisms are all very small organisms that can be cultured in petri dishes or incubators in the laboratory and are able to multiply in mitosis.
There is also a debate if viruses are living organisms or not. But if we look on the definition of “cell theory: all living things are composed of cells coming from pre-existing cells”. A virus is not a living organism since it is not made up of cells.
The virus consists of DNA or RNA surrounded by a layer of protein. Viruses are not considered living things because they can not reproduce themselves, and they are not composed of cells. What causes flu or a cold? The coughing and runny nose caused by one of the criminals is: virus. Viruses come in many forms. They are so small that they can only be seen with a very powerful microscope.
Curious, are there any "good" viruses that do helpful things (for humans)? (Also, nice posts! Very interesting)
