Bacteria(细菌) Bacteria are the most widely Gram +ve cell wall -flagellum distributed organisms in nature. It is composed of cell wall,cell inclusion body. membrane,cytoplasm,nuclear capsule body.Some bacteria have other ribosomes- special structures such as plasmid helical protein filaments -nucleoid capsule,flagella,and pili,etc. Most bacteria diameter are mesosome S-layer between 0.5 ~5um.Bacteria can be divided into three categories according to their shape:cocci, plasma mem peptidoglycan bacilli and spirochetes(including outer mem.- Gram-ve the arc-shaped bacteria).Also cell wall can be divided into G+,G. lipopolysaccharide pili This document is produced by trial version of Print2Flash.Visit www.print2flash.com for more information

Prokaryotes -Cell Wall From the peptidoglycan(肽聚糖)inwards all bacteria are very similar.Going further out,the bacterial world divides into two major classes (plus a couple of odd types).These are: Gram-positive Gram-negative 3 This document is produced by trial version of Print2Flash.Visit www.print2flash.com for more information
