Transcript 5 kingdoms
5 kingdoms 5 kingdoms • based on cells & source of Old food New Monera • prokaryotic organisms • simple 1 cell (few organelles) • Ex. bacteria, blue-green algae and cyanobacteria *no true nucleus prokaryote (genetic material scattered and not enclosed by a membrane) *some move (flagellum); others don't * some make their own food (autotrophic); others can't make their own food (heterotrophic) This video animation shows how a filamentous cyanobacterium uses its sheath and ability to move to defend itself against a ciliate grazer. Protista • eukaryotic organisms – can be photosynthetic, absorptive or ingestive. • Complex 1 cell (many organelles) • some move (cilia, flagella, pseudopodia); others don't • Ex. amoeba, diatom, euglena, paramecium, some algae (unicellular), etc Diatom species are identified by their unique shapes. An array of single-celled diatoms resembles a game of pickup sticks. Fungi • eukaryotes. Feed by absorption • non-motile • multicellular - cell wall but no chloroplasts *have nuclei *mainly do not move from place to place • rare in oceans Fungi Black Elongate areas Plantae • eukaryotes • Multicellular ~cell walls (cellulose) photosynthesis (chloroplasts) • Nonmotile • Ex. multicellular algae, seaweed, kelp, sea grass Animalia Animalia • Multicellular ~ no cell wall or chloroplasts • Motile • Ex. sponge, jellyfish, coral, fish, frog, bird, man • multicellular, ingestive Hierarchy of taxonomic categories • • • • • • • • Domain Kingdom Phylum Class Order Family Genus Species Eukarya Animalia Chordata Mammalia Cetacea Delphinidae Delphinus delphis AKA- dolphin Animalia
