Document Summary

Members of a species are similar (phenotype) to each other but different from other species: similarity of organisms in same species can be. Development (similar growth of embryos) ecological (occupy identical ecological niche) immunological (antibody against an antigen equally effective) (group of) organisms able to interbreed/reproduce giving fertile offspring: each species is reproductively isolated from every other species. Binomial: biological name of an organism genus species. Taxon: set of organisms within a category / taxonomy / study of biological classification. Different levels of taxons: species, genus, family, order, class, phylum, Kingdom: most number of species on right, most similar organisms on left. Unicellular: single cell; colonial: groups of cells; multicellular: many cells. Autotrophs produce energy from inorganic sources: phototrophs from photosynthesis/sunlight, chemotrophs from simple inorganic (oxidative) processes. Cell structure: prokaryotes, unicellular, prokaryotes lack cytoplasmic organelles found in eukaryotes. Divide by binary fission, not by mitosis. 10 m in size (bacterial cell, filaments of blue-green bacteria)
