Document Summary
Five kingdoms: monera, protista, fungi, plantae, animalia, and archaebacteria (1960s-1990s) Three domain system (dna analysis): bacteria, archaea, and eukarya (today) All are single-celled prokaryote w/ no internal membranes. Bacteria play a vital ecological role as decomposers. Bacteria play a vital role in genetic engineering (insulin-producing e. coli) Have a thick, rigid cell wall containing peptidoglycan. Methanogens: obtain energy in a unique way by producing methane from hydrogen. Halophiles: thrive in environments w/ high salt concentrations (ex: great salt lake) Thermophiles: thrive in very high temperatures (ex: hot springs, deep sea thermal vents) Superkindgom; contains four of the original kingdoms (protista, fungi, plants, and animals) All organisms have a nucleus and internal organelles. The four kingdoms of eukarya (cid:1035) must have general knowledge on characteristics and know some organisms from each! Includes widest variety of organisms, but all eukaryotes. Includes organisms that do not fit into the fungi or plant kingdoms (ex: seaweeds and slime molds)
