1. CLASSIFICATION OF ORGANISMS 6.12 D

2. HOW ARE LIVING ORGANISMS CLASSIFIED? We classify living organisms into a Domain and Kingdom based on the following characteristics: If they are… Unicellular or Multicellular Prokaryotic or Eukaryotic Autotrophic or Heterotrophic Mode of Reproduction: Sexual or Asexual

3. UNICELLUL AR Organisms made of only ONE cell. Ex: Bacteria, Archaea, Protista, Amoeba Hint: the word UNI=One

4. MULTICELLUL AR Organisms that are made of MORE than one cell. Ex: Animals, Plants and Fungi Hint: the word MULTI=Many

5. PROKARYO TIC An organism whose organelles (cell parts) do NOT contain a NUCLEUS. Very SIMPLE Structure Hint: Pro means NO Nucleus

6. EUKARYOTI C An organism whose cell parts have a NUCLEUS The “Eu” in Eukaryotic is pronounced “YOU”. Very COMPLEX Structure. Hint: “Eu”karyotic cells are like YOU…all of your cells have a NUCLEUS.

7. PROKARYOTIC VS. EUKARYOTIC Prokaryotic No Nucleus and Simple Structure Ex: Archaea and Bacteria Domain Eukaryotic Has a Nucleus and Complex Structure Ex: Eukarya Domain

8. AUTOTROP HIC Organisms that are capable of making their own food. Ex: Plants, Bacteria, Archaea and Protists.

9. HETEROTRO PHIC Organisms that can NOT make their own food. Ex: Animals, Humans, and Fungi

10. ASEXUAL REPRODUCTIO N Reproduction of a cell that does not require two parents, but only the cell making an exact copy of itself. Ex: Lizard regenerating its tail Ex: When you get a scab and skin cells reproduce to create new skin.

11. SEXUAL REPRODUCTIO N Reproduction of an organism that requires two parents to create new offspring. Ex: Babies, puppies, kittens
