BSCI-1510 Study Guide - Midterm Guide: Exothermic Reaction, Hydrophile, Ionic Bonding
Two classes of cells: prokaryotes and eukaryotes: prokaryotes = structurally simpler, include bacteria, before nucleus a. i. Still most abundant life form on planet a. iii. Eubacteria and archaebacteria are 2 domains that are prokaryotes a. iii. 1. Kingdom archaebacteria and eubacteria: eukaryotes =protists, fungi, plants, animals, true nucleus b. i. Mitochondria are proposed to have originated from a endosymbiotic relationship between an early eukaryote and a bacterium (combined into one cell) b. ii. 1. Mitochondria in present cells are similar to bacteria in many ways have their own genome (chloroplasts also have own genome) b. iii. All living organisms on earth evolved from common ancestral cells & are subdivided into 3 domains & 6 kingdoms: 3 domains = bacteria (eubacteria), achaea (archaebacteria), & eurcaryotes a. i. Reading: the origin of eukaryotic cells : endosymbioant theory = theory that describes the origin of mitochondria in. Eukaryotic cells: construct phylogenetic tree shows proposed pathway through which different groups of organisms may have diverged b. i.
