The ameba (also order amoeba) is a protozoan the belongs come the Kingdom Protista. The name ameba comes from the Greek native “amoibe”, which way "change". Protists are microscopic imreparable cells organisms the don"t fit right into the other kingdoms. Some protozoans are taken into consideration plant-like, such together algae, and also others are taken into consideration animal-like. The ameba is considered an animal-like protist because it moves and also consumes that food, however it is not classified as an animal because it consists of a solitary cell; the is unicellular.

Protists are additionally classified by how they move, some have actually cilia or flagella, yet the ameba has an unusual way of creeping along by stretching its cytoplasm into fingerlike extensions called pseudopodia. Words "pseudopodia" means "false foot". Top top the colour sheet, over there are number of pseudopodia, usage a yellow highlighter or pencil to highlight each of castle . When looking in ~ ameba under a microscope, one observer will view that no ameba watch the exact same as any other, the cabinet membrane is very flexible and permits for the ameba to readjust shape. Color the cell membrane red . Amebas live in ponds or puddles, and also can also live within people.

There are two varieties of cytoplasm in the ameba, the darker cytoplasm towards the internal of the protozoan is referred to as endoplasm, and the fingerprint cytoplasm that is uncovered near the cell membrane is called ectoplasm. Top top the coloring, the endoplasm is shown by the dotted area, and also the ectoplasm through the white area. Color the endoplasm blue , and leave the ectoplasm uncolored. By advertise the endoplasm toward the cell membrane, the ameba causes its body to extend and also creep along. That is also by this method that the ameba consumes its food. The pseudopodia expand out and wrap approximately a food particle in a process call phagocytosis. The engulfed food then becomes a food vacuole. Over there are several food secret on the drawing – color each brown . The food will at some point be spend by the cell’s lysosomes.

Also visible in the ameba is the nucleus, which consists of the ameba"s DNA. Shade the nucleus violet . In order come reproduce the ameba goes v mitosis, where the cell nucleus duplicates its genetic material and the cytoplasm splits into two brand-new daughter cells, each similar to the original parent. This method of reproduction is dubbed binary fission. An additional structure conveniently seen in the ameba is the contractile vacuole, whose project is come pump out excess water so that the ameba does no burst. Shade the contractile vacuole orange.

During unfavorable conditions, the ameba can create a cyst, this hard-walled body can exist because that a long duration of time till conditions end up being favorable again. In ~ this suggest it opens up and also the ameba emerges. Frequently cysts are created during cold or dry periods where the ameba can not endure in its common condition. Color the cyst green.

Amebas can cause disease. A common an illness caused by the ameba is referred to as Amebic Dysentery. A human being becomes infected by drinking contaminated water. The ameba then upsets the person"s digestive system and causes cramps and also diarrhea. A human is most likely to it is in infected in countries where the water is no filtered or purified.
