Dive into the characteristics of Domains Archea, Monera, and Eukarya, along with Kingdom Plantae, Fungi, Protista, and Animalia, as well as Classes Aves, Reptilia, Amphibian, Pisces, and Mammal in the world of biology.

Characteristics of domains, kingdoms, and classes discussed in class
Domain archea • Single celled • no membrane bound nucleus (prokaryotes) • Heterotroph/ few autotrophs • found in extreme environments
Domain Monera or bacteria • Single celled • Prokaryote ( no membrane bound nucleus) • Heterotroph/ few autotrophs • Have peptidoglycan in cell membrane • Examples • Strep throat, E coli, Salmonella
Domain Eukarya • Single or multicelled • Have membrane bound nucleus • Heterotrophs or autotrophs • Includes the following kingdoms • Plants • Animals • Fungi • protists
Kingdom Plantae • Multicellular • Autotrophs (have chlorophyll and are green) • Have cell walls • Two main groups • Vascular plants- trees, flowers • Nonvascular plants – moss, liverworts
Kingdom Fungi • Multicellular • Heterotrophs • Responsible for decomposition and recycling of nutrients back to soil. • Yeast, mushrooms, rusts, fruit molds • Penicillin comes from fruit molds
Kingdom Protista • These organisms do not fit in the other kingdoms of domain eukarya • They can be single or multicelled • Autotrophs or heterotrophs • Groups • Plant like – algae • Animal like – amoeba, plankton • Fungi like – slimey mildew, downy mildew
Kingdom Animalia • Multicellular • Heterotrophs • Includes invertebrates- corals, sponges, worms, insects, clams, spiders • Phylum chordata • Backbone and spine • Birds, reptiles, amphibians, mammals, fish
Class Aves (birds) • Feathers • Endotherm (warm blooded) • Hollow flight skeleton • Descended from dinosaurs • Lay eggs
Class reptilia • Dry scaly skin • Lay eggs (most) • Ectotherm (cold blooded) • Three chambered heart
Class amphibian • Smooth slimy skin • Ectotherm (cold blooded) • Breathe through skin • Have a aquatic life stage (gills) • Undergo metamorphosis • Have a land life stage (lungs)
Class Pisces (fish) • Paired Fins • Jaws • Gills for gas exchange (most do not have lungs) • May have a swim bladder for bouyancy • Most are ectothermic (coldblooded) • May lay eggs or give live birth
Class mammal • Have Hair/ fur • Endothermic (warm blooded) • Females make milk for young • Breathe air • Four chambered heart • Most give live birth with the exception of platypus and echidna which lay eggs
