It is sensitive to touch as well. Euglena is another gens of protists, containing green, unicellular, freshwater organism with a flagellum. Moreover, it consists of the characteristics of both animals and plants. That means; euglena has chloroplasts scattered throughout the cell. Therefore, when the light is available, it can undergo photosynthesis. Pyrenoids, which are micro-compartments inside the chloroplasts, operate carbon-concentrating mechanisms.
Also, Euglena stores food in the form of starch inside granules. Figure 3: Euglena. Furthermore, the animal-like characteristics of euglena include the presence of an eyespot, which detects light. It also lacks a cell wall. A protein layer is arranged around the cell known as a pellicle, providing flexibility and contractility to the cell. And, this pellicle is held by microtubules.
Moreover, the locomotion of Euglena occurs through the movement of flagella. The type of movement is known as metabolic. Its contractive vacuole is known as myoneme, and it helps in locomotion as well as excretion and osmoregulation. Figure 5: Euglena Structure.
Furthermore, Euglena is capable of undergoing photosynthesis while taking nutrients through ingestion into the cell. Therefore, it shows both autotrophic and heterotrophic characteristics.
Thus, the mode of nutrition in Euglena is mixotrophic. Amoeba refers to a single-celled animal that catches food and moves about by extending fingerlike projections of protoplasm while euglena refers to a green single-celled freshwater organism with a flagellum, sometimes forming a green scum on stagnant water.
Thus, this explains the fundamental difference between amoeba and euglena. While amoeba is free-living in damp environments or parasitic, euglena lives in freshwater and salt water. Above all, the main difference between amoeba and euglena is that amoeba moves by pseudopodia while Euglena moves by flagella. Amoeba does not have a defined shape while Euglena has a defined shape. Moreover, amoeba does not undergo photosynthesis while Euglena undergoes photosynthesis.
Another difference between amoeba and euglena is that the amoeba is a heterotroph while Euglena is a mixotroph. Amoeba is a free-living or parasitic protist. It moves by pseudopodia and ingests food particles through phagocytosis. If amebiasis is left untreated, however, it can be deadly. There are many home remedies for amebiasis available on the Internet. They range from increased fluid intake, coconut water, buttermilk, black tea, and herbal tea to garlic, Indian lilac, oregano, and apple cider vinegar.
Metronidazole is the drug of choice for symptomatic, invasive disease; paromomycin is the drug of choice for noninvasive disease. Altogether, this deadly infection is known as primary amebic meningoencephalitis PAM. Unless severely damaged by their environment or starved, amoebas are immortal. That is, they can indefinitely repair the normal wear and tear of living faster than it occurs. Amoebas are evidence that biology and death are not inseparable. Amoebas do not die because of age.
The amoeba consumes and digests its way into brain tissue, causing primary amoebic meningoencephalitis PAM. In pure water cleared of other microorganisms, the infective form of N. Initial symptoms of PAM start about 5 days range 1 to 9 days after infection.
The initial symptoms may include headache, fever, nausea, or vomiting. Later symptoms can include stiff neck, confusion, lack of attention to people and surroundings, loss of balance, seizures, and hallucinations. It is not possible for infections to occur by drinking contaminated tap water, and the amoeba is not known to be transmissible via water vapor or droplets in the air, such as shower mist, according to the CDC.
Furthermore, the infection cannot spread from person to person. Only 4 people out of known infected individuals in the United States from to have survived. PAM is a brain infection that leads to brain swelling and the destruction of brain tissue. The symptoms of naegleria infection generally begin within two to 15 days of exposure to the amoeba.
It thrives, multiplies and feeds on bacteria and is a life-threatening risk when the water temperature is warm, near 80 degrees and warmer. When water temps drop below 80, this amoeba could still be active and still pose as a risk. These conditions allowed the water and pipes to be colonized by Naegleria fowleri.
