Show 2.3.1 NO MAN IS AN ISLAND BECAUSE THEY ARE ACTUALLY A UNIVERSE (or even a galaxy) Let's do the Bacterial Breakdown: 1. Bacterium, n. Pronunciation: Brit. /bakˈtɪərɪəm/ U.S. /bækˈtɪriəm/ Forms: Pl. bacteria; rarely anglicized as bactery. Frequency (in current use): Etymology: modern Latin, < Greek βακτήριον, diminutive of βάκτρον stick, staff. Any of several types of microscopic or ultramicroscopic single-celled organisms very widely distributed in nature, not only in soil, water, and air, but also on or in many parts of the tissues of plants and animals, and forming one of the main biologically interdependent groups of organisms in virtue of the chemical changes which many of them bring about, e.g. all forms of decay and the building up of nitrogen compounds in the soil. 2. Bacteria, as the Oxford English Dictionary kindly points out, is plural for Bacterium. 3. The most accepted/used evolutionary model of phylogeny (the model that shows the evolutionary relationship between organisms) is the Three Domain System. In evolutionary order, those domains are: Archaea, Bacteria, and Eukaryotes. • Archaea and Bacteria are both Prokaryotes, or single celled organisms. Archaea are organisms that sound like their domain, archaic. Bacteria are the in between. Eukaryotes are multi-celled organisms, like plants and animals. Bacteria are important enough to have their own domain. 4. Bacteria were the first organisms to appear on Earth. 33 |
