Objective

This text provides an overview of the characteristics of organisms in Kingdom Animalia, including their multicellularity, eukaryotic cell structure, heterotrophic nature, mobility, and specialized organs. It also includes examples of animals such as Homo sapiens, Ursus maritimus, Uroplatus fimbriatus, Bathynomus giganteus, Trachinocephalus myops, Aye-aye, and Condylura cristata.

Presentation Transcript

  1. Objective • SWBAT describe characteristics of organisms in kingdom Animalia.

  2. Animals!

  3. Characteristics of Animals • Animals are multicellular. • They are eukaryotes. • They are heterotrophs (only consumers). • They are the only mobilemulticellular organisms. • They have complex, specialized organs. • Specialized: performs a specific function.

  4. Homo sapiens

  5. Ursus maritimus

  6. Uroplatus fimbriatus If disturbed, this gecko will raise its tail and head, open its mouth, and scream … to call its mother for help.

  7. Bathynomus giganteus (giant isopod) • Giant isopods live on the ocean floor – up to 6,000 feet deep – where there is no light. • They feast on dead and decaying fish that sink to the bottom of the sea.

  8. Check For Understanding • Which statement about animals is false? • They are multicellular. • They are eukaryotes. • They can produce their own energy. • Their cells have nuclei.

  9. Animal Cells • Animal cells do not have cell walls. More flexible than plants/fungi; can move on their own • Animal cells do not have chloroplasts.  Get food by eating other organisms.

  10. Trachinocephalus myops (snakefish) • Snakefish can grow to over 3 feet long. • They have a voracious appetite – they will eat all other fish in their lake or pond, even their own children. A snakefish can survive out of water for up to 3 days, slithering across land and eating small animals in its path.

  11. Check For Understanding • Which statement best describes a characteristic of the organisms in kingdom Animalia? • They thrive in extreme environments and lack a nucleus. • They contain cells that have a nucleus and lack a cell wall. • They are multicellular and use chlorophyll to manufacture food. • They are unicellular and depend on other organisms for energy.

  12. Sponges! But they can’t move! Actually, some species can – at speeds of about 1-4 millimeters per day, like an amoeba.

  13. Daubentonia madagascariensis(Aye-aye) The Malagasy people of Madagascar consider the Aye-aye to be magical, and they believe it brings death to any village it appears in.

  14. Check For Understanding • Which statement describes all members of the kingdom Animalia and some members of the kingdom Protista? • They are made of eukaryotic cells. • Their cells have cell walls. • They depend on other organisms for their energy. • They are autotrophs.

  15. What’s the difference? Amoeba proteus Aldabrachelys gigantae Mobile Eukaryote Consumer Multicellular, with complex organs • Mobile • Eukaryote • Consumer • Unicellular, with no complex organs

  16. Leptynia hispanica

  17. Check For Understanding • A walking stick is an insect that looks like a twig from a tree. Which characteristics are best used to classify the walking stick as an animal, and not a plant? • It is mobile, and it is a consumer. • It is multicellular and eukaryotic. • Its cells have nuclei and a cell membrane. • It reproduces and makes energy using sex cells.

  18. Puma concolor on Mr. D’s front lawn!

  19. Check For Understanding • Which statement identifies a difference between animals and fungi? • Animals are multicellular, but fungi are not. • Animals are hetertrophs, but fungi are not. • Fungi have chloroplasts, but animals do not. • Fungi have cell walls, but animals do not.

  20. Condylura cristata (star-nosed mole) This creature is blind. Its star-shaped snout has over 25,000 tiny sensory receptors that help it feel its way around, detecting food and predators.

  21. Animalia • Cell number: Multicellular (many cells) • Cell type: Eukaryotic (have a nucleus) • Energy: Heterotrophs (consumers) • Key fact: They are mobile and have complex organs. • Examples: humans, fish, insects, birds, sponges
