Cambridge, United Kingdom: The Press Syndicate of the University of Cambridge, 2001. While many of species of Amoeba can act as pathogens, the Amoeba proteus is non-pathogenic, and is not capable of causing disease in other organisms. In 1786, the Danish Naturalist Otto Müller described and illustrated a species he called Proteus diffluens, which was probably the organism known today as Amoeba proteus. discoides – A . [3], The Amoeba proteus exists in fresh-water aquatic environments, such as ponds, streams, puddles, or moist environments dominated by soil or plants. These have been studied since the very early days of microscopy and attempts were made to gain information on the [1] The Amoeba proteus is considered a polyploidy because it has more than 500 chromosomes in a single nucleus.

Besides granules, endoplasm contains a number of important inclusions such as a nucleus, contractile vacuole, food vacuoles, mitochondria, Golgi apparatus, fat globules, and plate-like or bi-pyramidal crystals. Some bubble-like vacuoles are seen in the endoplasm of Amoeba these are called a contractile vacuole. The sides of lotus ponds and the water troughs are excellent places for the collection of amoebae. The genome of a cousin, Amoeba proteus, has a mere 290 billion base pairs, making it 100 times larger than the human genome. A honeycomb-like lattice is found below the inner nuclear membrane which play important role in maintaining the flattened form of the nucleus. This is how the Amoeba proteus moves around. 14th Edition. it has definite anterior and posterior ends.

Other members of the subphylum Sarcodina, such as the radiolarians, heliozoans, and foraminiferans, usually possess protective coverings. Frequent change in the density of the plasmagel and plasmasol helps in producing pseudopodia. Oxygen diffuses through its surface membrane and through energy transaction, provides the organism with energy. [2], Other than its pseudopodia, the Amoeba proteus can be described as unicellular, colorless, or transparent. It is covered by the nuclear membrane made of protein and lipid. Zoology. About 600 microns; longitudinal is that the amoeboid way of life is extremely popular among the protists. Taxonomic Serial No. This small protozoan uses tentacular protuberances called pseudopodia to move and phagocytose smaller unicellular organisms, which are enveloped inside the cell's cytoplasm in a food vacuole, where they are slowly broken down by enzymes. 2018. This extending and contracting is from the reversible assembly of actin sub-unites into microfilaments. It is surrounded by a crowd of mitochondria, close to which tiny feeder vacuoles of water appear, which then combine to form a larger vacuole. Endoplasm contains the organelles of the cell. 24 Apr.
