The Microorganisms that will be studied in this course includes representatives of all microscopic life forms except, the viruses. Both stained and living representatives will be examined. They exhibit diverse characteristics morphologically and nutritionally. Considerable variations can be found in their shape, cellular structure, types of motility and size. They can be autotrophic and heterotrophic; chlorophyll- free and chlorophyll containing; unicellular and multicellular; saprophytic and parasitic; and ranging from bacteria to algae, fungi and protozoa. Some concepts of diversity of morphological types among organisms can be gained by careful microscopic examination of such specimen. Microorganisms Relative size Unicellular multicellular or Nucleus Reproduction Motility Present/absent Sexual/Asexual Bacteria Yeasts 1-2 microns 3-4 micrometers Unicellular Unicellular Absent Present Asexual Asexual Sexual and asexual Sexual and asexual Motile Non-motile Molds 3-40 microns 2 micrometers-60 meters Multicellular Multicellular unicellular Present Motile Algae and Present Motile Protozoa < 50 micrometers Unicellular Present Asexual Motile What is/are the characteristic/s common to each group of organisms observed? In terms of reproduction, all of the organisms above have the ability to reproduce asexually, but some organisms can also reproduce both sexually and exually. In addition, all of the organisms' relative sizes are so small that they need to be magnified with a tool to be seen. Of the organisms observed, which group was the largest? Which group was the smallest? Protozoa is the biggest group in terms of population, biomass, and variety, whereas bacteria is the smallest group.

Question

Give or make a conclusion:

What are the three forms of bacteria that you have observed? Discuss. Bacilli, spirals, and coccus are the three types of bacteria that I have noticed. Bacilli are rod-shaped bacteria. These bacteria are found in a variety of environments and can only be observed under a microscope. While spirals are bar-shaped and inflexible, coccus is spherical. What are the three forms of locomotive organs found in microorganisms? Discuss each. Cilia are an organism's initial locomotor organ. Its job is to transport water around the cell using the cilia. Prokaryotes and some eukaryotes have flagella. Another is pseudo or axopodia, which is a viscous liquid seen in amoebae. It captures prey. What is the most common characteristic of the algae? Discuss. An algae is a eukaryotic creature with no roots, stalks or leaves but has chlorophyll and other pigments that enable photosynthesis. They usually lived in water. They can be unicellular or multicellular, and they can reproduce sexually or asexual. Discuss the importance of these microorganisms in our lives and in nature. These bacteria are vital in delivering oxygen, carbon, nitrogen, and sulfur to all living things. Life would be impossible without it. Microorganisms also do over half of the photosynthesis on our planet, boosting oxygen levels and decreasing CO2. Microorganisms are vital to all living things because they give nourishment, guard against illnesses, and produce vitamins.
