Document Summary

Lasts about 1. 3 billion years of history of life. Perfect the basic cells known as bacteria. Linnaeus 5 kingdom theory: animalia, plantae, fungi, protista, monera. Kingdom monera: singles cells, includes all prokaryotes, no nucleus, first criteria. Kingdom protista: single cells, includes several groups of unicellular eukaryotes, cells fundamental unit of life and contain a nucleus. Heterotrophs came before autotrophs because mitochondria came first. Fungi absorb food, animalia eat food and plants make food. Eu prefix- true bacteria, real true nucleus. Morphological diversity: size, shape, mobility, metabolism. 3 very major groups by ribosomal sequences. Break up kingdom monera: origin of domain, difference in internal material, bactria. Eu means true chraracteristics: archea, eukarya. Archea: no peptidoglycan in cell wall, plasma membrane is branched with ether links, complex rna polymerases in translation, no nuclear envelope, circular chromosome, dna/histones, 1st amino acid was methionine.
