Biology Dictionary. They are also found in seawater that contains about 2.5% salt concentrations. Eukaryotic are multicellular organisms whose cell contains the nucleus and other organelles, while on the other hand, most prokaryotic are unicellular in which the nucleus is absent. Unlike the eukaryotic nucleus (which is surrounded by a nuclear envelope) the nucleoid is membrane-less, so the DNA is free-floating in the cytoplasm. So chromosomes/chromatin can be floating around anywhere with DNA inside the cell and that it doesn't need to be around a nucleus? [9] Euryarchaeota also demonstrate diverse lifestyles, including methanogens, halophiles, sulfate-reducers, and extreme thermophiles in each. 16 juin 2022 why do babies clap their feet. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. Other eukaryotes are sometimes called protists. These heavy metals are transformed into volatile methylated derivatives. https://www.khanacademy.org/science/high-school-biology/hs-cells/modal/a/prokaryotic-cells, Theory proposing that eukaryotic cells formed from a symbiotic relationship among prokaryotic cells, DNA is circular, usually free-floating in cytoplasm, Has nucleus and membrane-bound organelles (ie: mitochondria, chloroplasts, Golgi body, ER). However, Korarchaeota have many genes found in both Crenarchaeota and Euryarcheaota, and also genes which are different from both groups.
