Document Summary
Biomass and diversity of life - most are microbial. Know what molecules are most abundant in e. coli cell. Do not memorize electron tower of reduction potentials - need to know how to use it, how to know which are better electron receptors. Understand how horizontal/lateral gene transfer give rise to different microbes. Know ribosomal rna genes from mitochondria and plastid genomes are related to those from bacteria. Know examples of groups such as stramenopiles. Opisthokonts: closely related to animals and choanoflagellates. Many large and are multicellular or coenocytic: many with large fruiting bodies. Important in decomposition: many parasites, many beneficial symbionts. Immotile: non-flagellated: most are filamentous with hyphae (sing. A mass of hyphae = mycelium: has a cell wall - predominantly made with polysaccharide consisting of chitin. Provides strength and supports penetration into material/hosts o. Filamentous form gives very high surface area to volume ratio.
