Animal kingdom
- 2. Characteristics of all Animals • They are made of cells, which form tissues, which form organs which form organ systems. • They obtain food by eating other organisms (herbivores, carnivores or omnivores). • Most animals reproduce sexually but some can reproduce asexually.
- 3. •All animals move in order to satisfy 1 of their basic needs (food, water, shelter, escaping danger)
- 4. Types of food eaters Carnivore - meat eater (either a predator - prey relationship or a scavenger) Herbivore - plant eater Omnivore - eats plants and meat
- 6. Animals have bilateral symmetry (1 line that can divide the animal into 2 identical parts) or radial symmetry ( many lines that can divide the animal into equal parts).
- 7. Sub Kingdom: Invertebrates • Sponges • Cnidarians • Worms
- 8. Sponge • Simplest form of animal • No tissues or organs • heterotrophic & cells that have specialized jobs • Bodies pierced all over with openings called pores
- 9. How do Sponges eat & breathe? • Collar cells on the inside of central cavity trap bacteria & protists & digest them. • Sponges get O2 by diffusion.
- 10. Cnidarians • Specialized tissues - no organs. • Radial symmetry
- 11. Digestion • Capture prey using stinging cells to inject venom - paralyzes prey • Pull prey into mouth, digest in body cavity digestive system: 1 opening - expel food from mouths also.
- 12. Reproduction • asexually by budding & sexually. • Some have both sexes within 1 individual others in separate individuals. • Examples include jellyfish, sea anemones and coral.
- 13. Worms • Flatworms (Platyhelminthes) • Roundworms (Nematoda) • Segmented worms (Annelida)
- 14. All Worms… • Have tissues, organs and organ systems. • Have bilateral symmetry. • Have a brain. • Reproduce both sexually and asexually. • Can replace parts by a process called regeneration.
- 15. PHYLUM MOLLUSCA Clams, snails, squid, octopus
- 16. Most mollusks have a hard shell covering their soft bodies. Clams have a wedge-shaped muscular foot used for locomotion.
- 17. PHYLUM CHORDATA Fish, amphibians, reptiles, birds, mammals
- 18. Members of Phylum Chordata have a backbone (they are vertebrates).
- 19. Class Chondrichthyes includes fish whose skeletons are made of cartilage, such as sharks, rays, and skates. Fish
- 20. Class Osteichthyes includes fish whose skeletons are made of bone.
- 21. Class Amphibia includes semi-aquatic animals with moist skin. They must return to the water to breed. Amphibia
- 22. Class Reptilia includes snakes, lizards, turtles, crocodiles, and iguanas. They have dry, scaly skin. Reptiles
- 23. Members of Class Aves have wings and feathers for flight. Birds
- 24. Class Mammalia includes animals with hair or fur. Females have mammary glands to nurse their young with milk. Mammals
