BIOL 1123 Lecture Notes - Lecture 36: Cell Wall, Plant, Thermophile
Document Summary
Taxonomy: field of biology concerned with the theory, practise and rules of classifying living organisms and viruses. Systematics: study of biological diversity and the evolutionary relationships among organisms, both extinct and modern. Hierarchy: system of organization that involves successive levels. In biology, every species is placed into several different groups. Kingdoms > phyla > classes > orders > families > genera. All life forms are grouped within 3 domains: bacteria, archaea and. Eukarya includes 4 eukaryotic kingdoms: proctista, fungi, plantae and. The 3 domains share strikingly similar characteristics, such as: w w w w w w. All species use the same genetic code mrna encodes information to produce proteins trna and ribosomes are needed to synthesize proteins, using mrna are a source of genetic information. All living cells are surrounded by a plasma membrane. Certain metabolic pathways such as glycosides are found in all 3 domains. Can survive on many different sources of energy.
