  1. Diversity of Organisms Diversity of Organisms kingdom vertebrate invertebrate vascular nonvascular fungus bacteria protist

  2. kingdom How are living things grouped together? How are living things grouped together? kingdom (king´dәm)The broadest group into which organisms are classified.

  3. vertebrate invertebrate What do animals have in common? vertebrate (vûr´tә brit) An animal that has a backbone. invertebrate (in´vûr´tә brit) An animal that does not have a backbone.

  4. What do animals have in common? Vertebrates Invertebrates

  5. vascular nonvascular What do plants have in common? vascular (vas´kyә lәr) Containing vessels that transport water and food. nonvascular (non vas´kyә lәr) Containing no plant tissue through which food or water moves. Vascular Nonvascular

  6. fungus What are fungi? fungus (fung´gәs) Members of a kingdom that cannot make their own food and must absorb it from their environment. Fungi

  7. bacteria What are bacteria? bacteria (bak tîr´ē ә) Unicellular organisms that have cell membranes but no distinct nuclei. Ancient Bacteria True Bacteria

  8. protist What are protists? protist (prō´tist) A member of the kingdom Protista, which contains mostly unicellular organisms with distinct nuclei. Plant-like Animal-like Fungus-like

  9. Review Main Idea How is the animal kingdom divided? The animal kingdom is divided into vertebrates, which have backbones, and invertebrates, which do not have backbones. Vertebrates are divided into five classes: fish, amphibians, reptiles, birds, and mammals. There are different phyla of invertebrates, including sponges, mollusks and arthropods.

  10. Review Main Idea How are organisms in the plant kingdom divided? Plants are divided into vascular and nonvascular.

  11. Review Main Idea How are bacteria classified? Details Main Idea The two kingdoms of bacteria are the ancient bacteria, which are generally found in harsh environments, and true bacteria, most of which live in or on other organisms. Ancient bacteria – hot springs bacteria True bacteria – pneumonia, Lyme disease

  12. Review Vocabulary Match each word with its definition. vascular kingdom vertebrate invertebrate A) an animal that has a backbone B) the broadest group into which organisms are classified C) containing vessels that transport water and food D) an animal that does not have a backbone

Review Vocabulary Match each word with its definition. protist nonvascular fungi bacteria A) a member of the kingdom Protista, which contains mostly unicellular organisms with distinct nuclei B) containing no plant tissue through which food or water moves C) unicellular organisms that have cell membranes but no distinct nuclei D) members of a kingdom that cannot make their own food and must absorb it from their environment

  14. Review Reading Diagrams How are plants divided?
