Chapter 4: Characteristics of procaryotic and eucaryotic Cells staple Cell Types prokaryotic Cells eukaryotic Cells Evolution of Endosymbiosis The front by Substances Across Membranes staple fibre Cell Types Prokaryote: wiz- carrelled organisms, and every are bacteria. eucaryote: noncellular or multi-cellular organisms Pro = before Eu = true Karyon = nucleus Similarities: plasma membrane, deoxyribonucleic acid and cell wall ( level cells) Differences: Eukaryotic DNA is in a nucleus butt against by a thermonuclear membrane prokaryotic DNA is in a nuclear instalment not surrounded by a membrane Table 4.1:Similarities and Differences amid Prokaryotic/Eukaryotic Cells Prokaryotic cells give a single measure chromo or so; Eukaryotic cells have diametrical chromosomes Prokaryotic cells overlook histone proteins; Eukaryotic cells have histone proteins Prokaryotic cell wall has peptidoglycan; plant and fungal cells have both cellulose and chitin Domains A relatively overbold innovation in biological classification, plain is the highest category Three domains: Archaea (ancient) bacteria (eubacteria) Eukarya Size, roll and Ar framement Prokaryotes are among the smallest of all organisms Prokaryotes range from 0.5 2.0 µm in diam and from 1.
0 60 µm in length Exception: 1991- Epulopiscium fishelsoni is a bacterial symbiont of sturgeon fish (80 µm in diameter and 600 µm in length Arrangements of Bacteria coccus in pairs (diplococci): Neisseria sp. Cocci in bonds (streptococci): Streptococcus sp. Rods in chains: Lactobacillus sp. Cocci in clusters: staph sp. An Overview of Structure Structurally, bacterial cells brood of the following: Cell membrane, normally surrounded by a cell wall Internal cytoplasm with ribosomes, nuclear region, and in some cases, granules and/or vesicles Capsules, flagella, and pili...If you want to shell a full essay, hallow it on our website:
