The Are Tiny Single Cell Organisms Essay

Imagine if someone approached you and said that nothing in this world exists? Now, you can believe that this person is crazy, and that this individual has no right to say nonsense. An argument can be made that things do exist because we exist. We wake up, whether we want to or not, progress through the day, go to sleep, and repeat the process until our lives come to an end. Those who are religious argue God created man and everything around, and that what we distinguish now. Those who oppose the religious statement argue the idea of evolution and we all originate from a single celled organism. Each of these statements are limited for their justifications are supported by religion or science. Philosophically, both of these statements are

There are many parts of a cell, they all have specific duties, and are all

Bacteria are single celled organisms. Some classify them as a separate (fourth) kingdom on the tree of life.

Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful.

Bacteria - are micro-organisms that consist of only one cell. Bacteria multiply by splitting themselves in two, which is called a binary fission. Because of this they can increase in number rapidly. The majority are harmless, but some can be pathogenic which results in bacterial infection occuring. Bacterial infections can be treated by using antibiotics. Bacteria can evolve a resistance to antibiotic e.g. MRSA. Some diseases caused by bacteria include tuberculosis, pneumonia, salmonella, tetanus and syphilis.

The article “Some of My Best Friends are Germs,” by Michael Pollen was a very interesting and informative read. Pollen explains that our bodies house 100s of trillions of microbes. More than 99 percent of our genetic information is microbial. The large number of bacteria that inhabits us weighs many pounds, forming a massive, unexplored world that scientists are just starting to document. These bacteria affect our health as much as if not more than the genes we receive from our parents.

Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.

Microbes are bacteria, archaea and eukaryotes. The earth was formed 4.6 million years ago. And a few million years later, by 3.5 billion years ago, earth was already inhabited by a diversity of organisms. The earliest organism is Prokaryotes and within the next billion years, two distinct groups of prokaryotes called bacteria and archaea diverged. Eukaryotes cell evolved from a prokaryotes community, a host cell containing even smaller prokaryotes .The microbial world accounted for all known life forms for nearly 50 to 90% of Earth's history. We are still researching microbial organisms today in marine environment, extreme environments. A microbial observatory is an NSF-funded project dedicated to the discovery and characterization of novel microorganisms and microbial communities of diverse

Before, biologists assumed all microbes are bad for the human body (automatically thought of pathogens), caused many diseases and harm our body fundamental systems. In addition, the biologists think that our body is already built which had all the functions required to maintain our health. However, the attitude has changed over the last decade. The biologists characterized the most prevalent species of microbes in the body, and found out that these collective microbes do not threaten us, and they also are important part of human bodies.

There are many bacteria that do not go through cellular respiration; there are also some that do. These tiny organisms live in every habitat, including the air we breathe. Prokaryotes are grouped according to their need for oxygen. Obligate anaerobes are prokaryotes that cannot live in the presence of oxygen. In fact, exposure to oxygen for even a short length of time will kill these prokaryotes. They produce methane and are found at the bottom of lakes, in marshy areas, and in the digestive tracts of herbivores and omnivores. Bacteroides are a species of obligate anaerobic bacteria that live in mammalian intestines and help break down lipids and proteins into their smaller subunits, monomers. Clostridium difficile bacteria are often found

Microbes are everywhere and anywhere. Microbes can be found from on surfaces of our daily lives to microbes we encounter and spread on. Microbes have been always since life started in this planet. According to a BBC article about Earth, “…an older microbe came to light…to be a remarkable 3.5 million years” (BBC). As stated, microbes may be considered to have been here long before any other living organism, which means these microbes have evolved through time as well. With evolving comes the different types of bacteria that may benefit us and also harm us. Harmful bacteria such as Lyme disease and the Plague which both derive from an infected insect with different bacterium. These two different disease made different approaches to our history

Bacteria are classified as microbes,which are single celled prokaryotic organisms that are invisible to the naked human eye. As diverse as humans are, microbes are even more so, having been on Earth 1,000 times longer than human beings, a total of 3.5 billion years. Because of this, microbes have evolved to inhabit practically all environments on this planet, from extreme high and low temperatures, no oxygen content, or

When we speak of the word “bacteria” some individuals may not recognize how large of a role these tiny organisms play in our everyday lives. Some may jump to the conclusion that bacteria are related to the spread of germs or sickness among the human population. Most microbes are harmless or beneficial (Matthews, 2015) and a large majority of these tiny microbes are extremely important in order to maintain the balance of living organisms and chemicals in our environment (Tortora, Funke, & Case, 2013).

Microbiology is a subject dealing with microbes and related concepts. Microbiology has come a long way since discovery of microbes and is presently of great help to mankind. It is used in health care, food production, diagnosis, production of alcohol, maintenance of sterility and cleanliness etc.

Life on this planet began with microorganisms. Through millions of years microorganisms have found ways to successfully adapt and survive. These adaptations have created a wide biodiversity, allowing them to basically populate in all places. Why are these microbes so important? Because they shape the history of our world. Some microbes can be deathly to humans while some others are favorable, for example, bacteria that lives in the gut of both humans and animals and helps during the process of digestion (Alfred Brown & Heidi Smith, 2006). Understanding these interactions help scientists to find ways to protect humans from potential deathly pathogens. In order to observe microbes, microscope proficiency and microorganisms’ identification are crucial skills in a microbiology lab. During this laboratory session, samples of environmental and human organisms were inoculated into two different rich media and incubated to their according temperature. After this, appropriate use and calibration of the microscope was performed. Lastly, morphology and size of different species of bacteria, algae, fungi and protozoan were recorded.
