Document Summary
Taxonomy: system used to name and classify organisms, living and extinctcarl linnaeus. Binomial nomenclature: every organism has a two-part name. Hierarchy of taxa, or levels of organization. Kingdom, phylum, class, order, family, genus, species. Kingdom is the most general first five kingdoms: monera, protista, fungi, plantae, and animalia today there is a three-domain system: bacteria, archaea, and eukarya. All single celled prokaryotes no internal membranes. Bacteria are vital decomposers that recycle dead organic matter. Genetic engineering: human intestine bacteria help make human insulin. Conjugation: primitive form of secual reproduction individuals exchange genetic material thick, rigid cell wall containing peptidoglycan. No introns (noncoding regions within the dna) Methanogens: obtain energy by producing methane from hydrogen. Halophiles: thrive in environments with high salt concentrations. Thermophiles: thrive in very high temperatures introns present in some genes. All organisms have a nucleus and internal organelles. The four kingdoms of eukarya: protista, fungi, plants, and animals. Heterotrophs (amoeba and paramecium) and autotrophs (euglenas)
