  1. Continuing Section 1.3:III. BIOTIC Parameters

  2. 1. Cell Types Prokaryotic Eukaryotic Larger cell More advanced Organelles True nucleus More complex reproduction in series of steps • Small • Primitive cell • No organelles • Not true nucleus • Grow and reproduce quickly • Bacteria is one form

  3. A car classification example might be: • Motor vehicle • Car • Ford • Mustang • V-6 • Convertible • red

  4. Classifications • Scientists use systems to group and classify • Linnaeus Classification System • extinct and living species of organisms • grouped species by physical characteristics

  5. Linnaeus Classification System Classification order: Ex: Human Classification Animal Chordata(vertebrate) Mammal Primate Hominidae Homo Sapien • kingdom • Phylum • Class • Order • Family • Genus • Species

  6. Kingdoms – classified based on FEATURES that they share

  7. The Kingdom Monera • unicellular • prokaryotic • Many biologists now divide the Monera Kingdom into 2 kingdoms: • a. Eubacteria - true bacteria; commonly found in soils, water or living in or on other organisms (present everywhere) • Ex: blue green algea

  8. b. Archeobacteria • inhabit extreme conditions such as hot springs or ocean depths • thought to be the most primitive prokaryotes (1st to exist)

  9. Purple sulfur bacteria - Archeobacteria

  10. 2. KindomProtista unicellular eukaryotic usually move by cilia, flagella, or by amoeboid mechanisms. may have chloroplasts. small, although many are big enough to be recognized with a magnifying glass. Nutrients: decomposer, preditors, autotrophic

  11. Types of Protozoas: a) ciliates – move by hairlike structure Ex: paramecium

  12. Paramecium going through Binary fission Paramecium

  13. b) amoebas – move by pseudopods

  14. c) flagellates – smallest protozoa; have one or more flagella (long whiplike tail)

  15. d) plankton (drifting organisms such as jellyfish) • zooplankton – animal like; • ameoba, paramecium • phytoplankton – plant like;

  16. e)slime molds – like fungi and animals

  17. 3. Kingdom Fungi multicellular eukaryotic Nutrients: from absorbing foods; decompose dead organisms; do NOT perform photosynthesis do not move Ex: mushrooms, puff balls and molds

  18. 4. Kingdom Plantae multicellular eukaryotic Nutrients: produce own food (autotrophs) photosynthetic

  19. 5. Kingdom Animalia(1.5 million in category) multicellular eukaryotic Nutrients: obtained from ingestion (heterotrophs) have organelles including a nucleus, but no chloroplasts or cell walls they move

  20. a) invertebrates – no backbone 97% of all animal species Ex: worms, insects, spiders, mullusks

  21. b) vertebrates – backbone Ex: snakes, turtles, frogs, humans
