Kingdom Animalia

Cards (42)

  • Kingdom animalia

    part of domain eukarya
  • Animal attributes
    • heterotrophic
    • made of eukaryotic cells
    • no cell walls
    • multicellular
  • body plan
    arrangement of physical features that contribute to structure and form
  • bilateral symmetry
    can be divided by a plane through its center to create mirror images
  • radial symmetry
    have no left and right sides and can be divided by a plane through their center in several places to form mirror images
  • no symmetry
    asymmetrical
  • Animal Attributes
    • Nutrition
    • Support
    • Respiration
    • Reproduction
    • Circulation
    • Movement
  • nutrition
    all animals need food for growth and energy
  • how do animals get nutrients?
    • ingestion of food
    • breaking down food by digesting
    • egesting waste products
    • excreting nitrogenous waste produced during digestion through urinating
  • respiration
    • animals need to exchange gases in order to keep life processes going
    • they have organs for inhaling air and exhaling carbon dioxide as a waste product
  • circulation

    animals transport materials through their bodies to get nutrients to where they're needed (e.g. blood)
  • movement
    animals have locomotion using appendages, some are sessile
  • support

    animals have no cell walls, therefore they need skeletons
  • hydrostatic skeleton

    some aquatic animals use their watery environment to fill cavities in their body for support. collagen is an important part
  • endoskeleton

    skeleton inside the body
  • exoskeleton

    stiff outer covering
  • reproduction

    animals can reproduce their own kind sexually, asexually ,or both
  • invertebrates
    • no backbone
    • cover 30 phyla
    • 97% of animals
  • vertebrates
    • have backbone
    • phylum chordata
  • endothermic
    • uses metabolism and complex internal systems to maintain homeostasis and regulate temperature
    • have insulating layer (e.g. feathers)
    • different temperature with their environment
  • ectothermic
    • uses behavior to regulate temperature
    • body temperature is near to environment temperature
    • cold blooded
  • torpor
    a temporary hibernation, both ecto and endothermic animals slow down bodily processes to drop temperature and escape extreme temperatures
  • zygotes undergo division to form a ball of cells called blastula
  • blast pore

    a bunch of hole where cells from the wall of blastula go through to get inside of blastula
  • what is formed because of the inward movement of cells into the blastula?
    germ layers
  • germ layers
    layers of cells that influence the structure and processes of the body
  • germ layers
    • ectoderm
    • mesoderm
    • endoderm
  • ectoderm
    forms outer layer including outer covering and related systems
  • mesoderm
    middle layer, muscle and circulatory system
  • endoderm
    inner layer, forms digestive track
  • radial animals
    2-3 germ layers
  • bilateral animals
    3 germ layers, have cephalization
  • cephalization

    concentration of sensory and nerve cells (e.g. mouth at head, anus at rear end)
  • external fertilization
    egg is fertilized outside of mother's body
  • internal fertilization
    egg is fertilized inside of mother
  • oviparous
    zygote develops in an egg
  • ovoviviparous
    zygote develops inside an egg inside of mother's body
  • viviparous
    develops inside of mother's womb
  • behavior
    ways an animal responds to environment
  • instinct
    built-in response to the environment
