Presentation Transcript
sponges1
Sponges
  • Transport and excretion: Diffusion
  • Gas exchange: Respiration
  • Nutrition: Filter feeders
  • Reproduction: Sexual
  • sponges
cnidarians1
Cnidarians
  • Transport and excretion: Diffusion
  • Respiration: Aerobic respiration
  • Digestion: Use nematocysts for digestion
  • Reproduction: Asexual or sexual
  • Nematocyst
  • Box Jelly
flatworms1
Flatworms
  • Transport and excretion: Digestive tract (finally!)
  • Respiration: Aerobic respiration
  • Nutrition: Mouth and digestive tract (but only one opening!!!)
  • Reproduction Growth and Development: Sexual reproduction externally
  • Flatworm sex
  • tapeworm
transport and excretion
Transport and excretion
  • Transport and excretion: closed circulatory system for transport and nephridia for excretion
mollusks
Mollusks
  • Respiration: Gills or lungs (depending if on land or in water)
  • Nutrition: Filter feeder or through mouth (radula)
  • Reproduction: Sexually externally
transport and excretion1
Transport and Excretion
  • Closed circulatory system, digestive system and anus
segmented worms1
Segmented Worms
  • Respiration: Skin
  • Nutrition: Mouth and anus
  • Reproduction: Sexually using eggs and sperm
  • Annelids
arthropods

Arthropods

Insects, crustaceans and arachnids

transport and excretion2
Transport and excretion
  • Open circulatory system (they are small)
  • Digestive system and anus
respiration
Respiration
  • Tracheal tubes, spiracles, book lungs or gills in underwater crustaceans
nutrition
Nutrition
  • Mouthparts specialized for eating
reproduction
Reproduction
  • Sexually internally or externally
  • Praying Mantis male gets eaten
  • Barnacle
slide20
Fish
  • Transport and excretion: Closed circulatory system, digestive tract, anus, urinary tract
    • Small intestine absorbs most nutrients
  • Respiration: Gills
  • Nutrition: Mouth with jaws for eating (first one!)
  • Reproduction: Sexually mostly external fertilization
amphibians

Amphibians

Frogs and Salamanders

amphibians1
Amphibians
  • Transport and excretion: closed circulatory system, digestive tract, anus, urinary tract
    • Small intestine absorbs most nutrients
  • Respiration: gills as tadpoles, lungs and skin as adults
  • Nutrition: Jaws with long tongue
  • Reproduction: Sexually external fertilization
reptiles
Reptiles
  • Transport and excretion: Closed circulatory system, digestive tract, anus, urinary tract
    • Small intestine absorbs most nutrients
  • Respiration: Lungs
nutrition1
Nutrition
  • Specialized jaws
reproduction growth and development
Reproduction, growth and development
  • Sexual reproduction internally and produce amniotic eggs
birds1
Birds
  • Transport and excretion: Closed circulatory system, complete digestive tract, anus, urinary tract
    • Small intestine absorbs most nutrients
  • Respiration: Lungs with air sacks
  • Nutrition: Beaks or bills for obtaining food
  • Reproduction growth and development: Internal sexual reproduction and form a hard amniotic egg
placental mammals
Placental Mammals
  • Transport and excretion: Closed circulatory system, complete digestive tract, anus, urniarytract
    • Small intestine absorbs most nutrients
  • Respiration: Lungs
  • Nutrition: Jaws with different types of teeth
  • Reproduction: Sexually with placenta to give birth to live young
marsupials
Marsupials
  • Everything is the same as placental mammals except they give birth to young very early and the young live in their pouch
monotreme
Monotreme
  • Transport and respiration are the same….
  • but they have long snouts or duckbills for nutrition and lay eggs for reproduction
