Explain How Microbes Are Involved In Energy Flow

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

According to Margulis, the pre-eukaryotic cell engulfed an aerobic bacterium, but rather than digest and kill the bacterium, a symbiotic relationship was born. This relationship, the aerobic bacterium provided energy through ATP and the eukaryotic cell provided an environment to live while protecting the new symbiont from harm in environmental factors such as oxygen. Because almost all living eukaryotes have a mitochondria, it is safe to assume that this event happened before plants and animals split in the evolutionary lineage.After this first evolutionary leap came a

* Cells allow things to go in and out of the organism (allows diffusion to happen so good things go in and bad things go out)

For many years the identification of microorganisms has been important in the world of medicine. It is essential or correct disease diagnosis in patients and for proper treatment. Knowing the correct identity and characteristics of microorganism is crucial when disease outbreaks occur in populations, also knowing how humans can benefit from microorganisms is important; many can be used in making certain foods or antibiotics.

This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others make antibiotics used today. This lab was completed by using the methods learned thus far in identification of bacteria.

Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.

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.

In order for growth to occur microorganisms need to obtain energy. One of those ways is by either the use of oxygen or not using oxygen. Microorganisms that require oxygen are obligate aerobes. It is essential for

2.At Earth's beginning, there was no oxygen, so the cell that used the anaerobic process had to learn to function without oxygen and because of that there was a lot of anaerobic respiration occurring since no organism can survive without oxygen.

Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

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.

Cells, they are the building block of all life, they are what make up the entirety of living things on Earth and without them living things would cease to exist. It is because of this that cells are considered to be the most important known unit of life and are studied so often. Cells were first observed in the mid 17th century by English physicist and microscopist Robert Hooke using on of the earliest versions of the microscope. (Biologyreference.com, 2017) Hooke’s observations led to further investigations and studies into the topic of cells resulting in many major breakthroughs in the field of biology. Possibly the biggest of these breakthroughs is credited to have being made by Theodor schwann, Matthias Schleiden and Rudolph Virchow,

Microbes were the abundant biological entities found in the biosphere. Identification and measurement of microorganisms (including viruses, bacteria, fungi and protists) cannot be completely achieved due to limitations in culturing methods. Micro organism communities were important in the functioning of all ecosystems, but the unculturable microorganisms and their role in natural ecosystems were unclear. Metagenomics was based
