The ameba (also order amoeba) is a protozoan the belongs to the Kingdom Protista. The surname ameba originates from the Greek word “amoibe”, which means "change". Protists room microscopic imreparable cells organisms the don"t fit into the other kingdoms. Part protozoans are thought about plant-like, such as algae, and also others are considered animal-like. The ameba is thought about an animal-like protist since it moves and consumes its food, however it is no classified as an pet because it is composed of a single cell; it is unicellular.

Protists are also classified by how they move, some have cilia or flagella, but the ameba has an unusual method of creeping follow me by stretching its cytoplasm right into fingerlike extensions dubbed pseudopodia. The word "pseudopodia" method "false foot". Top top the colour sheet, over there are number of pseudopodia, use a yellow highlighter or pencil to to mark each of them . As soon as looking at ameba under a microscope, an observer will view that no ameba watch the same as any kind of other, the cell membrane is really flexible and allows for the ameba to adjust shape. Color the cell membrane red . Amebas live in ponds or puddles, and also can also live within people.

There are two types of cytoplasm in the ameba, the darker cytoplasm toward the internal of the protozoan is dubbed endoplasm, and the fingerprint cytoplasm the is discovered near the cabinet membrane is referred to as ectoplasm. On the coloring, the endoplasm is indicated by the dotted area, and also the ectoplasm by the white area. Shade the endoplasm blue , and also leave the ectoplasm uncolored. By advertise the endoplasm toward the cell membrane, the ameba reasons its human body to extend and creep along. It is also by this method that the ameba consumes its food. The pseudopodia prolong out and also wrap roughly a food bit in a procedure call phagocytosis. The engulfed food climate becomes a food vacuole. There are number of food vacuoles on the drawing – color each brown . The food will ultimately be digested by the cell’s lysosomes.

Also clearly shows in the ameba is the nucleus, which contains the ameba"s DNA. Color the nucleus purple . In order come reproduce the ameba goes with mitosis, whereby the cell nucleus duplicates its genetic material and the cytoplasm splits right into two brand-new daughter cells, each similar to the original parent. This technique of reproduction is referred to as binary fission. One more structure easily seen in the ameba is the contractile vacuole, whose task is come pump the end excess water so that the ameba does no burst. Color the contractile vacuole orange.

During unfavorable conditions, the ameba can create a cyst, this hard-walled body have the right to exist because that a long period of time till conditions end up being favorable again. In ~ this allude it opens up and the ameba emerges. Regularly cysts are developed during cold or dry durations where the ameba could not endure in its normal condition. Shade the cyst green.

Amebas can cause disease. A common condition caused through the ameba is dubbed Amebic Dysentery. A person becomes infected by drink contaminated water. The ameba climate upsets the person"s digestive system and causes cramps and diarrhea. A human being is most likely to be infected in countries where the water is not filtered or purified.
