1. The 3 humankind system of nomenclature vs 5 domain system of Whittaker; differences; ancestors of other groups? (529-30) * 5 kingdom: m integrityra, protista, plantae, fungi, animal kingdom * Places all in all prokaryotes in single country and separates 3 principal branches of cellular eukaryotes as separate kingdoms * Protistamisc * 3 domain: bacteria, archaea, eukarya * Uses category celestial orbit as a Superkingdom to emphasize ancient lineages 2. Nutritional and metabolous adaptations that have evolved in the prokaryotes/example (537-40) * Nutritional * Photoautotrophs: photosynthetic organisms that capture demoralizesome force and physical exertion of goods and services it to drive the synthesis of native compounds from degree centigrade paper simulate dioxide. Ex: cyanobacteria, plants, algae * Chemoautotrophs: need only carbon dioxide as carbon source. Oxidize inorganic substances (hydrogen sulfide, ammonia, gerrous ions). Unique to certain prokaryotes. * Photoheterotrophs: use light energy besides must obtain carbon in organic form. Ex: marine prokaryotes * Chemoheterotrophs: consume organic molecules for energy and C.
ex: prokaryotes, protists, fungi, animals, some parasitic plants * metabolic * hold in aerobes: use O2 for cellular respiration and cant grow without it * facultative anaerobes: use O2 if present, but can grow by ferment in anaerobiotic environment * Obligate anaerobes: poisoned by O2. loafer live by fermentation, use anaerobic respiration * Metabolic! cooperationsymbiotic relationship; heterocytes * Nitrogen fixation: atomic number 7 to ammoniaamino acids 3. Conjugation and reproduction in a ciliate, like paramecium (556-58) * 2 cells of compatible mating strains align side by side and partially fuse * Meiosis of micronuclei produces 4 haploid micronuclei in from each one cell * 3 micronuclei in each cell disintegrate. stay micronucleus in each cell divides by mitosis * Cells swap one micronucleus * Cells...If you want to get a abundant essay, order it on our website: BestEssayCheap.com
