Six Kingdoms of Life 3 Domains of Life https://www.youtub e.com/watch?v=BnD RJAt-4aM Six Kingdoms Archaea Bacteria Protists Fungi Plants Animals Prokaryotes Versus Eukaryotes https://www.yout ube.com/watch?v =RQSMCmWB1s&list =PL6CmKEkVCe8ctij0kj4mq0j SJmdqWuu4&ind ex=3 Archaea Oldest form of life Singe cell organism (unicellular) Have no nucleus or membrane bound organelles Are more closely related to Eukaryotes despite their Bacteria like appearance 3 common types: • -Thermophiles, live in the hot springs or in deep sea vents • -Halophiles, live in salty environments like the Dead Sea or in salt lakes • -Methanogens, live in methane rich environments like swamps or stomachs, are anerobic and produce methane Examples of Extremophile Environments Bacteria Second oldest form of life Prokaryotic, single cell organism (unicellular) Contains no membrane bound nucleus or organelles like mitochondria Have single chromosome Reproduce asexually by binary fission (splitting in two) Familiar examples of bacteria • Streptococcus • Staphylococcus https://www.youtube.com/watch?v=j8_xo M8Wwgs Difference Between Bacteria and Archaea (Prokaryotes) Archaea Cell membrane contains ether linkages Cell wall lacks peptidoglycan Bacteria Cell membrane contains ester bonds Cell wall made of peptidoglycan Genes and enzymes behave Have only one RNA more like Eukaryote polymerase Have three RNA polymerases React to antibiotics in a like eukaryotes different way than Archaea do Extremophiles Protista “Odds and Ends” kingdom A diverse taxonomic group and especially a kingdom (Protista) of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi (as slime molds). https://www.youtube.com/watch?v=zsdYOgTbOk Fungi Types of Cells: Unicellular and Multicellular Fungus is eukaryotic and has cell walls. • Decomposer, feed on dead or decaying tissue. Fungi digest food by releasing enzymes to break down organic matter into a form the https://www. fungus can absorb. youtube.com Type of Reproduction: – Asexually reproduces with SPORES. /watch?v=k WSYawl0KjQ Plantae Multi-cellular organisms Most plant organisms contain chlorophyll. Cell walls of plant cells are comprised of cellulose. Plants have both organs and organ systems. They obtain their energy from sun through photosynthesis. Plants reproduce both by sexual and asexual. Plants develop a self defense mechanisms. Organisms within Kingdom Plantae are multicellular, eukaryotic and autotrophic. Lack of motility. If you don’t know what a common plant looks like your in trouble….. Animalia All animals are multicellular, eukaryotic heterotrophs —they have multiple cells with mitochondria and they rely on other organisms for their nourishment. Adult animals develop from embryos: small masses of unspecialized cells Simple animals can regenerate or grow back missing parts Most animals ingest their food and then digest it in some kind of internal cavity. If you don’t know what a common animal looks like, your in even bigger trouble….
