  1. ANIMAL KINGDOM Pgs. 294-302

  2. All members of the Kingdom Animalia have the following characteristics: Type of cells: EUKARYOTIC Cellular organization: MULTICELLULARType of reproduction: ASEXUAL/SEXUALFood production: HETEROTROPHIC BY INGESTION The angler fish The Kiwi bird, although only the size of a chicken lays an egg that weighs about 1 pound!. The Aye-Aye is a nocturnal animal that lives in Madagascar.

  3. Animals are Multi-Cellular Let’s Review: Cells: basic unit of structure and function in living things are arranged into….. Tissues: similar cells that perform a specific function are arranged into…… Organs: group of several different tissues are arranged into…... Organ systems: groups of organs that perform a broad function

  4. All animals, no matter their size, appearance or habitat they live in carry out the SAME functions. • Get food and oxygen • Keep internal conditions stable • Move • Reproduce

  5. Animals EAT! • Animals have certain adaptations that allow them to eat a certain diet. • Ex. fangs. talons, claws, pinchers, sharp teeth, etc. • Being heterotrophic gives an animal energy for breathing and moving. • Digestion is internal • Food is broken down INSIDE the body. Manatees are herbivores and can fill 90% of their lungs with oxygen. This allows them to stay under water for 20 minutes feeding on plants.

  6. Animals and Homeostasis • Animals MUST maintain a stable environment inside their bodies in order to survive. • Body temperature • Levels of oxygen in blood • Levels of sugar in the blood

  7. Animals Move! • All animals move AT SOME POINT IN THEIR LIVES. • Animals move to meet their basic needs • Make and maintain a shelter • Find food • Get water • Find a mate Coral is an animal that is stationary during its adult life but moves during its early stage of life.

  8. Animals Reproduce! • Sexual reproduction: the fertilization of an egg by sperm • (2 sex cells join) • Asexual reproduction: a new organism reproduces another organism similar to itself • (one parent)

  9. Classification of Animals • The animal kingdom is divided in to phyla. • All vertebrates are divided into one phylum, while all the other invertebrates make up the remaining animal phyla.

  10. Animals are classified by their body structure, DNA, and how it develops.

  11. BASIC BODY CHARACTERISTICS OF ANIMALS Body symmetry - the way body parts are arranged around a point or central axis. Directions on the body - used to describe areas on the body of an animal. Pattern of body development - a sequence of developmental steps. Formation of germ layers - layers of specialized cells in the early development.

  12. BODY SYMMETRY BILATERAL - THE BODY CAN BE DIVIDED INTO TWO IDENTICAL HALVES BY ONLY ONE SPECIFIC PLANE THROUGH THE LONGITUDINAL AXIS.

  13. BODY SYMMETRY RADIAL - THE BODY CAN BE DIVIDED INTO TWO IDENTICAL HALVES BY ANY PLANE THAT PASSES THROUGH THE LONGITUDINAL AXIS.

  14. BODY SYMMETRY ASYMMETRICAL - THE BODY HAS NO DEFINITE SHAPE AND CANNOT BE DIVIDED INTO TWO IDENTICAL HALVES. Sea sponge is asymmetrical

  15. DIRECTIONS ON AN ANIMAL BODY DORSAL - TOP SURFACE ANTERIOR - FRONT END POSTERIOR - HIND END VENTRAL - BOTTOM SURFACE

  16. Developmental Stages • ZYGOTE-THE FERTILIZED EGG. • 2. EMBRYO-THE DEVELOPING FERTILIZED EGG. • 3. FETUS-THE EMBRYO HAS DEVELOPED TO THE POINT THAT IT BEGINS TO RESEMBLE THE MATURE ORGANISM.

  17. Vertebrate embryos look alike in their early development

  18. GERM LAYERS • What is a germ layer? • Specialization of body tissues in common animals. • 2 or 3 germ layers may develop while the animal is forming • These cell layers become specific structures and organs in the animal.

  19. a.ECTODERM-CELLS ON THE OUTSIDE THAT BECOME THE BODY COVERING. b.MESODERM-A MIDDLE LAYER OF CELLS THAT FORMS MUSCLES AND INTERIOR ORGANS. c.ENDODERM- INSIDE CELLS THAT FORM THE GUT
