Document Summary
Classification of bacteria: difficult to classify: mode of nutrition how they metabolize resources, ability to produce. Resistant bodies that contain dna & small amount of cytoplasm surrounded by. Flagella = apical/posterior/engulf cell or corkscrew motion or gliding through. Cocci - spherical / bacilli - rod-shaped / spirilla-spirochetes - spirals: shapes, thick peptidoglycan wall cell = gram-(+) thin peptidoglycan covered w/lipopolysaccharides = gram (-) Photosynthetic like plants use chlorophyll a/split water/release o2/etc. Some have specialized heterocysts cells that produce nitrogen-fixing enzyme. = converts fixed inorganic nitrogen gas into nh3 used to make amino acids & Nucleotides *ex: blue-green algae-not related to other prokaryotic algae groups. Autotrophs = some nitrifying bacteria no2- no3- Heterotrophs = fix n2 & lives in nodules of plant *mutualism. C- domain eukarya - 4 kingdoms pafp & *subcategories =phylum. Artificial kingdom used mainly for convenience/poorly understood - mostly unicellular.
