Presentation Transcript

  1. 2/12 • Pick up the packet from desk. • Get out your content frame and warm up sheet • Bring me your Protist/Fungi worksheet to get it stamped.

  2. Warm up • Which two levels of classification are used to name an organism? • What is one characteristic shared by a virus and a living cell? • What characteristic distinguishes Fungi from Plantae?

  3. No warm up today • Read through the instructions for today’s lab with your table partner

  4. Ready slide and clip You will want to look at this part under the microscope. Hint: corners are the best place to look.

  5. Diatom • The other one is on a premade slide at the front of the room. Amoeba 

  6. INTRO TO THE ANIMAL KINGDOM

  7. What is an Animal? Characteristics of All Animals 1. Animals are Multicellular 2. Animals are Eukaryotic 3. Animals are Heterotrophs 4. Animal cells lack cell walls

  8. Evolutionary/Developmental Milestones in Animals • Cellspecialization and levels of organization • Development of body symmetry and segmentation • Development of an internal body cavity and tissue layers

  9. Cell Specialization Cells throughout a multicellular organism can develop in different ways to perform different tasks.

  10. Levels of Organization

  11. Body Symmetry Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry… • Radial Symmetry:A body plan in which all body parts of an organism are arranged around a central point • Bilateral Symmetry:a single plane divides the body into two mirror images • Asymmetry:cannot be divided into mirror images

  12. Body Segmentation Segmentation of the body allows development of various specialized limbs, such as antennae, pincers, walking legs, claws, wings, etc. Cephalization is the concentration of nervous tissues in one location which eventually produces a head region with sensory organs and a brain.

  13. Tissue Layers & Body Cavity The significance of having a body cavity, or a coelom, is that it increases the efficiency of food intake and waste removal.

  14. The Animal Kingdom is divided into two main groups… Invertebrates & Vertebrates

  15. Porifera

  16. Invertebrates • Over 95% of all animal species are invertebrates • There are 8 major phyla of invertebrates from the simplest to the most complex…

  17. Invertebrates

  18. Invertebrates

  19. ANIMAL BODY SYSTEMS Body systems are all interrelated and work together to perform their functions in animals. Body systems can be organized and studies by these functions: • REGULATION: Excretory & Nervous Systems • NUTRIENT ABSORPTION: Respiration, Digestion, & Circulatory Systems • DEFENSE: Immune, Integumentary, Lymphatic, Skeletal, & Muscular Systems • Reproduction: Reproductive & Endocrine Systems
