1. DOMAIN KINGDOM PHYLUM CLASS ORDER FAMILY GENUS SPECIES Classification Levels

2. BUDDING - asexual

3. CONJUGATION - sexual

4. Classification levels – 3 Domains/6 Kingdoms Domain: Archaea Kingdom: Archaebacteria - prokaryotes; unicellular with a cell wall - can be autotrophs or heterotrophs - most live in extreme/hostile environments; open ocean - reproduce asexually (binary fission) or sexually (conjugation) *binary fission = cell divides *conjugation = transfer of DNA through a tube

5. Domain: Bacteria Kingdom: Eubacteria -prokaryotes; unicellular with a cell wall - can be autotrophs or heterotrophs - some bacteria cause disease; many are beneficial - live almost everywhere - reproduce asexually (binary fission) or sexually (conjugation)

6. Classification levels – 3 Domains/6 Kingdoms Domain Eukarya Kingdoms: Protista, Fungi, Plantae, Animalia

7. The Six Kingdoms

8. The Six Kingdoms: Archaebacteria Eubacteria Protist Fungi Plant Animal

9. How are organisms placed into their kingdoms?  Cell type, complex or simple  Their ability to make food or not  The number of cells in their body

10.  Cell wall  No cell wall  Prokaryote-cells do not have a nucleus  Eukaryote-cells contain nucleus  Heterotroph-organism cannot make its own food  Autotroph-organism can make its own food  Multicellular-organism contains more than one cell  Unicellular-organism is made of only one cell 5 t h i n g s w e n e e d t o k n o w t o c l a s s i f y a n o r g a n i s m i n t o k i n g d o m s

11. Eukaryote Some have no cell walls. Cell walls; some have chloroplast Most unicellular; some multicellular Autotroph or heterotroph “Junk-drawer kingdom”; live in water or damp environments Reproduce asexually(fission,budding) or sexually(conjugation)

12. Eukaryote Cell walls Most multicellular;some unicellular Heterotroph Water or damp environments Reproduce asexually(budding) or sexually(spores)

13. . Eukaryote Cell walls Multicellular Autotroph live in water and on land reproduce asexually(plantlets;runners) and sexually (pollination)

14. Eukaryote No cell walls Multicellular Heterotroph live in water and on land reproduce asexually(budding) but mostly sexually(egg/sperm)

15. Why and how do scientists classify organisms? to make sense and order of the millions of living things on Earth; to make organisms easier to study!! groups organisms based on characteristics they share “taxonomy” – the science of classifying and naming a scientific name consists of a “Genus” name followed by the “species” name common name:scientific name: cat ------------------------Felis domesticus asian elephant-------------Elephas maximus T-rex-----------------------Tyrannosaurus rex

16. “dichotomus keys” – a tool/ special guide using paired statements to help identify an organism; means divided into 2 parts example: 1. a. This mammal flies; hand forms wing little brown bat b. this mammal does not flygo to step 2 2. a. this mammal has no hair on its tailgo to step 3 b. this mammal has hair on its tail go to step 4 (and so on and so on………)

17. a growing system……….. new organisms are STILL being discovered and classified today!
