Microorganisms Essay

Microorganisms are a part of every productive soil; there is no soil that is without microorganisms. Without the work of microorganism there would be no soil. While microorganisms work they begin to make the soil more fertile. This makes for a better plant environment. Most microorganisms can photosynthesize, so they do not need to find their own food (Franzmeir).

Microorganisms also thrive on plant nutrients. Some microorganisms can only survive if they are attached to plant roots, although most function freely. All microorganisms need moisture, air, a favorable temperature range, and most of the same nutrients as a plant. Microorganisms also live and thrive in different temperature ranges. For example, psychrophiles grow at a temperature

They also grow faster then they can replicate their DNA. Microorganism have many layers. The cell wall, which is made of peptidoglycan gives each species its different shape. From the inside of the cell to the outside there is the inner membrane; also known as the plasma membrane.Next, comes the cell wall. Finally, there is the outer membrane and envelope. The microorganism’s shape is determined on the envelope (Properties of Microbes)

Microorganisms are beneficial to our environment. They produce the oxygen that humans breathe. That amounts to around 50% of all oxygen in the Earth’s atmosphere. Microorganisms are also responsible for breaking down dead organisms, animals, waste, and plant litter. The Earth would be filled with corpses without them (Properties of Microbes).

There are many different types of microorganisms. Amoeba are a type of Protozoa. They are found in ponds, lakes, streams, rivers, ocean backwater estuaries, and even rain puddles. The prefer to be in water with high oxygen levels, but will be able to survive in water with normal oxygen levels. They are also found in large food webbed areas, that contain lots of algae and plants. Also, because of its dislike of light, it usually finds shade under lily pads (Amoeba

These heat loving Protozoa can only enter a human through the nasal passage. There are also amoeba that are harmless like proteus amoeba. They are a eukaryotic microorganism that clean and purify water. The amoeba is also unicellular and transparent. They are the largest amoeba and can almost be seen by the naked eye; they are anywhere from five-hundred to one-thousand micrometers long. They can contract onto any other shape, which is common in eukaryotic microorganisms. Amoeba proteus can also sense light. They sense the light they tend to move away from it. Within fifteen minutes of sensing light, the amoeba will split in two (Collecting and Culturing
