    Microbial Diversity and Ubiquity Microorganisms are microscopic organisms that are so small that that they can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because

They are so widespread that they can be found in such extreme environments as the top of mountains‚ the bottom of oceans and even the surface of our skin. Bacteria are single-celled microorganisms that can exist as independent organisms or in conjunction with a host as a parasite. A bacterium lacks a nucleus‚ mitochondria‚ and chloroplasts; however‚ it still manages to carry out respiration and photosynthesis. Bacteria are defined by

    Unknown Experiment Introduction: The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test‚ and the very first one done‚ is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified‚ the tester has a wide array of differentiating tests at their disposal. Based on the results from these

    INTRODUCTION Microorganisms such as bacteria‚ fungus‚ mold‚ and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar‚ which creates an ideal environment for the organisms to form colonies‚ which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms‚ it is necessary to use the magnification of a high-powered microscope. These techniques
