Other protists use flagella or cilia instead of pseudopods. The Euglena is similar to the Amoeba. The Euglena moves its whole body into one pseudopod and the Amoeba only moves a fraction of the body into it. Amoebas and paramecia share the common traits of being single-celled organisms, being heterotrophs, and reproducing through mitosis. Similar to euglena, volvox has an eyespot which helps to sense light. Volvox is photosynthetic; hence, it makes its own foods.
Moreover, volvox feeds on algae and many different kinds of plants. Volvox colonies move with the help of flagella. Amoeba and paramecium are two unicellular eukaryotes. Moreover, the asexual reproduction of amoeba occurs either by binary fission and the formation of spores.
Under favorable conditions, binary fission produces daughter cells by mitotic cell divisions of a parent cell. Spores are formed in dry or unfavorable conditions and during insufficiency of food. Furthermore, amoeba is sensitive to external stimuli such as the change in light, temperature, and chemicals. 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. Carolina's innovative, proprietary tissue fixative produces superior specimens with life-like tissue texture and color.

Mine activities, information, and helpful hints for ESS. Trendy 3-D special effects on movie screens grab and keep your students' attention. Now use their fascination with mutli-dimensions to discuss visual perception, optics, and colors while studying the solar system.
This demonstration is dedicated to raising your students' awareness of the air pollution created by their everyday activities. Teach a class like forensic science where you have to apply physics, chemistry, and biology content?
We have interdisciplinary activities and tips to help. This brief guide will provide you with the information you need to make a number of solutions commonly used in educational laboratories. In this activity, students engage in a game of beanbag toss—but instead of merely keeping score, they explore statistical concepts such as mean, median, mode, and range.
This author provides an excellent student lab-report format, explains how it adapts to different science disciplines, and suggests simple labs to familiarize students with it. Keep your classroom or lab safe throughout the schoolyear with lots of helpful tips, hints, and safety techniques. You have questions-we have answers.

But in others, the parasite attacks the gut itself and can cause potentially fatal diarrhea, intestinal ulcers, and liver abscesses.
To kill amoebas and cysts confined to the intestine, three drugs called luminal drugs are available: iodoquinol Diquinol and others , paromomycin Humatin and diloxanide furoate Furamide.
One of these drugs is used along with metronidazole when gastrointestinal symptoms are present. You may eat soft, plain foods. Good choices are soda crackers, toast, plain noodles, or rice, cooked cereal, applesauce, and bananas. Eat slowly and avoid foods that are hard to digest or may irritate your stomach, such as foods with acid like tomatoes or oranges , spicy or fatty food, meats, and raw vegetables.
Amebiasis generally responds well to treatment and should clear up in about 2 weeks. If you have a more serious case where the parasite appears in your internal tissues or organs, your outlook is still good as long as you get appropriate medical treatment.
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.
