Kingdom Animalia pg. 406 new text Biology 11
Characteristics pg. 408 new text • Multicellular, heterotrophic, eukaryote • Most: Sexual Reproduction • Aquatic and terrestrial • Cell membrane • No cell wall
Classified in various ways pg. 408 new text • 1. Presence of a vertebral column • 2. Body Symmetry – none, radial or bilateral • 3. Body Cavity (cœlome) • 4. Body layers - two or three layers • 5. Body Organization – tissues, organs, organs systems • 6. Digestive tract or gut – one opening or two
1. Vertebral column pg. 408 new text • 2 Groups: • Vertebrates (have a notocord at some stage of their life) • Invertebrates (do not have a notocord) • 95% of all animals are invertebrates • ~ 30 different phylum of invertebrates
2. Body Symmetry pg. 406 new text • 2 Types: • Bilateral Symmetry: A shape has bilateral symmetry if one half of the shape is the mirror image of the other. Ex. humains, sharks, and ants. • Radial Symmetry: A shape has radial symmetry if the shape of one part is repeated several times abut a central axis. Ex. starfish, jellyfish, sand dollar
2. Body Symmetry pg. 410 new text • How is body symmetry related to an animal’s lifestyle and brain development? • Cephalization: the concentration of nerve tissue and receptors at the anterior end of an animals body. • Latin for “cephalicus”, meaning head
3. Body Cavities or Coelom pg. 409 new text • Coelom: the fluid filled space inside the body, lined with a layer of cells called the peritoneum, it contains and protects body organs. • 3 Types: • Coelomates • Acœlomates • Pseudocoelomates
3. Body Cavities or Coelom pg. 409 new text • Coelomates – Animals containing a true coelom lined with continuous peritoneum. Ex: Round worms, Frogs, Humans • Acœlomates - Animals lacking a true coelom or body cavity. Ex: Sponges, hydra and flat worms. • Pseudocoelomates - Animals containing a fluid filled space of variable shape and has no peritoneum
4. Body layers (germ layers)-pg. 408-409 new text • Germ layers: layers of cells in the embryo that give rise to specific tissues in the adult. • There are three different types of germ layers: • Ectoderm • Endoderm • Mesoderm
4. Body layers (germ layers)-pg. 408-409 new text • Ectoderm: ecto = outer and derm = skin or layer. • Skin and nervous tissue. Hair and nails etc. • Endoderm: endo = inner • Lining of the gut • Mesoderm: meso = muscle • Organs of the systems
Summary of major Phyla of the Animal Kingdom pg 411 new text • Porifera (sponges) – redbeard sponge • Cnidaria – jellyfish and hydra • Platyhelminthes (flatworms) - tapeworms • Nematoda (roundworms) – hookworm • Rotifera (wheel animals) – rotifer • Annelida (segmented worm) – earthworm • Mollusca (mollusks) – snails, clams, squids • Arthropoda (arthropods) –insects, lobster • Echinodermata – strafish, sea cucumbers • Chordata (chordates) – fish, amphibians, reptiles, birds, mammals
Nematoda (roundworms) pg 419-421& 427 new text • A Microfilariae (larval worms) of a parasitic nematode roundworm being attacked by cells of the immune system
