Domains & Kingdoms Life Science
Domains & Kingdoms Objective: • Identify and explain the three domains • Identify and explain the six kingdoms Let’s begin by reviewing some key terms
Captures energy from the sun or other chemicals Producer Depends on other organisms to get energy Consumers Autotrophs vs. Heterotrophs Getting Food
Does have a membrane-bound nucleus Many organelles CELL TYPE Eukaryote vs. Prokaryote • Does not have a membrane- bound nucleus • Few organelles
Uni- one Organism is made of only one cell Multi- many Organism is made of many cells Unicellular vs. Multicellular BODY TYPE
Reproduction Asexual Reproduction • One Parent • Offspring look exactly like parents • The primary form of reproduction for single-celled organisms such as archaea, bacteria, protists, • Many plants and fungi reproduce asexually as well
Reproduction Sexual reproduction • Two parents • Offspring look different from parents • Occurs in plants and animals
Three Domains • Eubacteria • Archaeabacteria • Eukarya
Eubacteria • Some bacteria in this domain can cause health problems like strep throat and food poisoning • Other bacteria are good to eat, such as those in yogurt • Some change milk into cheese!
Archaebacteria • All organisms in this domain live without oxygen • They also live in very hot or acidic environments Examples are: • Great Salt Lake or The Dead Sea • Sulfur Spring - hot, acidic waters • Sewage Treatment Plant • Geysers in Yellowstone
Eukarya • Includes all of the organisms with eukaryotic cells – they have a nucleus! • This domain contains most of the organisms we know best • This domain is divided into four kingdoms!
Kingdoms Six Kingdoms -organized according to type of cells, ability to make food, number of cells in body • Archaebacteria • Eubacteria • Protists • Fungi • Plants • Animals
Archaebacteria -”ancient bacteria” -existed before dinosaurs -live in extreme environments -hot springs -acidic environment -methane -unicellular prokaryotes -some autotrophs, some heterotrophs
Eubacteria Chemical makeup is different from that of archaebacteria. -unicellular prokaryote -some autotrophs, some heterotrophs
Protists -“odds and ends” kingdom because its organisms are pretty different from one another -most unicellular, some multicellular -eukaryotes -some autotrophs, some heterotrophs
UNICELLULAR & MULTICELLULAR PROTISTS
Fungi -mushrooms, mold, and mildew -most are multicellular, some (like yeast) are unicellular -eukaryotes -all are heterotrophs -eat dead or decaying organisms
Plants -all plants are multicellular -all are eukaryotes -plants are autotrophs
Animals -all are multicellular -all are eukaryotes -all are heterotrophs
