Taxonomic Groups A sampling of key organisms

Major Taxonomic groups n n n n Domain Kingdom Phylum Class Order Family Genus species

Domains n n Larger/more inclusive than Kingdoms Most biologists agree on three domains: Archaea, Bacteria, and Eukarya Archaea and Bacteria (also termed PROKARYOTIC) Tiny, unicellular (mostly), simple, lacking organized nucleus. PRO, NO nucleus Eukarya: larger, more complex cells, have an organized nucleus and membrane bound organelles. Can be single or multicellular. YOU are EUkaryotic

KINGDOMS n n n Monera Protista Fungi Plant Animal

Monera n n Bacteria Blue-Green Bacteria (formerly and incorrectly called Bluegreen algae) n n n Primitive cell structure Lacks nuclear membrane, membrane bound organelles Ex. E. Coli, Streptococcus, Staphylococcus

Protista n n Protozoa Algae n n Animal like Plant like Most are unicellular, simple eukaryotes Ex. Ameba, Paramecium, Green Algae

Protist Pictures

FUNGI n Cells usually organized into branched, multinucleated filaments that absorb digested food from the environment. Have cell walls usually made of Chitin n Ex. Yeast, Bread mold, Mushroom

Fungi

There’s a fungus among us!

PLANTS n n Bryophytes: Lack vascular tissue (tubes), have no true stems, roots, leaves Tracheophytes: Have vascular tissue, true roots, stems, leaves n n Ex. Moss, liverworts Trees, ferns, flowers, veggies
