They are shapeless, and the largest of these organisms may grow to a size of 1 mm. Amoeba mostly thrive in moist environmental conditions, such as soil, bottom of freshwater ponds, puddles, streams, and seawater, or as parasites in animals, including humans. The cells of the amoeba contain special features. Their cytoplasm and cellular contents are enclosed within a cell membrane. Their DNA is packaged into the nucleus. Finally, they contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport. It is interesting to know how an amoeba moves itself because the process is completely different from normal locomotion process of other living beings. An amoeba propels itself by changing the structure of its body. Basically it's the cytoplasm and its variation that helps aid in locomotion of the organism. Amoeba also extends the sides of its body to help rise special structures known as pseudopods, which enables it to "drag" itself. These extended structures, known as pseudopodium not only aid in locomotion but also help in capturing prey. When the cytoplasma flows towards the end, the pseudopodium also extends and the amoeba drags itself. The pseudopodium is also referred to as false feet and it can develop from any part of the body. It grows in size and engulfs its prey by a technique known as phagocytosis. They shrink when …show more content…
They transform into a cyst below the temperature of 10°C.
As a trophozoite, it moves around to find bacteria it can feed on. And it grows the fastest at a temperature of 42°C. When it comes in contact with the human brain, it starts destroying the tissues and digests red blood cells and white blood cells.
This amoeba takes the form of a flagellate when it is looking for a better environment to live in. This amoeba does not really target a human, but it is in search of bacteria for food. When a human consumes water in which these amoebas are present, either by drinking, swimming or bathing, the amoeba finds its way to the brain, through the hosts nose. The scariest part is, that the survival rate for the resulting infection is only
