  1. The Animal Kingdom

  2. Characteristics of Animals • Eukaryotic • Multicellular • Reproduce • Specialized Cells • Heterotrophic (must obtain food) • Must Digest Food • Most animals move and have a fixed size in the adult form

  3. B C A ANIMAL PHYLA

  5. Classification of Animals Symmetry: AssymetricalRadialBilateral Body Cavity: AcoelomatePseudoceolomateCoelomate Embryonic Openings ProtostomeDeuterostome

  6. Symmetry

  7. Body Symmetry of Animals

  8. Asymmetrycannot be divided into mirror images • Ex- sponges • Very simple organisms • Believed this type of organism evolved 1st

  9. Radial Symmetry:can be cut in half along many planes that allow for nearly identical halves Ex- Hydra: adaptation to be able to see prey coming at it from any direction

  10. Bilateral Symmetry:a single plane divides body into two mirror images More complex organisms exhibit this kind of symmetry

  11. Proto/Deuterostomes • Deuterostomes • Radial Cleavage • Blastopore becomes the __anus_____ • Indeterminate Cleavage: which means early on in development the fates of the cells are undetermined • Protostomes- • Spiral Cleavage • Blastopore becomes the ____mouth___ • Determinate Cleavage- which means that each cell of the embryo has a fixed or determined fate.

  12. How else do we classify Animals? DNA Coelom or not Physical Characteristics

  13. Body cavity

  14. Acoelomates • FLATWORMS (Phylum _________) • May be the 1st organisms to evolve organs from mesoderm • Solid, compact body • Organs imbedded in the solid tissue of the body. • first to have the three cell layers • Ecto/endo/mesoderm • Have a digestive tract (one way gut)

  15. Pseudocoelomates • Roundworms (Phylum _________) • Have a body cavity • It’s fluid-filled and partly lined with mesoderm • Enables animal to move more quickly • Muscles attach to the mesoderm and brace against the pseudocoelom

  16. Coelomates • Segmented worms (Phylum ______) • Coelom provides space for development of organs/ organ systems • This allows for membranes like the parietals and viscerals Have a TRUE body cavity • COELOM= fluid-filled space COMPLETELY surrounded by mesoderm. • Coelom cushions and protects internal organs and provides room for them to grow and move independently

  17. Digestive Tube Ectoderm Endoderm Mesoderm Coelom Do You Have A Cavity???

  18. Get ready to CLICK!!!
