Title: Animals


1
Animals
  • Quarter 4 Week 4

2
Intro to Animals
  • Multicellular, heterotrophic, eukaryotic
    organisms.
  • Most have specializationadaptation of a cell for
    a particular function
  • Most reproduce sexually

3
Animals
  • Most move in some way at some point in their life
    (sessiledoes not move, ex. Sponges are sessile
    as adults)
  • Movement is due to the relationship between two
    unique (animals only) types of tissuenervous and
    muscular tissue
  • Originated from the sea probably evolved from
    loosely connected, flagellated protists.

4
Phylum Porifera
  • Examples

5
Phylum Porifera
  • What is their symmetry? Asymmetrical
  • Where do they live? Water
  • How do they travel? Sessile
  • How do they feed? Filter
  • How do they reproduce? Most sexually
  • Define regeneration regrowing a part that has
    broken off.

6
Phylum Cnidaria
  • Examples

7
Phylum Cnidaria
  • What is their symmetry? radially
  • Where do they live? ocean
  • How do they travel? Swim as adult
  • How do they feed? Capture prey
  • How do they reproduce? Both sexually and
    asexually

8
Flatworms
  • Examples

9
Flatworms
  • What is their symmetry? bilateral
  • Where do they live? Moist area or water
  • How do they travel? Crawl, swim
  • How do they feed? Parasitic and feeding tube
  • How do they reproduce? hermaphrodites

10
Phylum Mollusca
  • Examples

11
Phylum Mollusca
  • What is their symmetry? bilateral
  • Where do they live? Damp places or water
  • How do they travel? Swim, crawl
  • How do they feed? Filter feeder, capture,
    radulas
  • How do they reproduce? Sexually

12
Phylum Annelida
  • Examples

13
Annelida
  • What is their symmetry? bilateral
  • Where do they live? Almost everywhere except
    frozen soil
  • How do they travel? Shortening and lengthening
    its body
  • How do they feed? Mouth to gizzard
  • How do they reproduce? hermaphrodites

14
Arthropoda
  • Arachnid Crustaceans insects

15
Phylum Arthropoda
  • What are 3 classes? Insects, crustaceans,
    arachnids
  • What is their symmetry? bilateral
  • Where do the live? everywhere
  • How do to they feed? Mandibles, Chelicerae,
    sucking
  • How do the Reproduce? sexually
  • Define exoskeleton hard outer covering
  • Define Metamorphous series of changes from
    juvenile to adult

16
Phylum Chordata
  • Vertebrates are a subphylum of Chordata they
    have backbones
  • --classes of vertebrates include fish (several
    types), amphibians, reptiles, birds, mammals.

17
Phylum Chordata
  • At some stage in life all chordates have
  • A notochord
  • Dorsal hollow nerve cord
  • Pharyngeal pouches (gills)
  • Post-anal tail

18
Class Fish
  • Examples
  • Chondrichthyes and Osteichthyes

19
Fish
  • What are the differences in each class?
  • What are examples?
  • Where do they live? Water
  • How do the reproduce? Sexually, external
    fertilization
  • How many chambers do their hearts have? 2

20
Amphibia
  • Examples

21
Amphibians
  • Where do they live? Double life part water part
    land
  • How do they reproduce? Sexually, eggs need water,
    external fertilization
  • What does Amphibian mean? Double life
  • How many chambers is in their hearts? 3

22
Reptilia
  • Examples

23
Reptiles
  • What are the major Characteristics? Scales, legs
    for walking, sharp claws
  • Where do they live? land
  • How do they reproduce? Sexual, eggs dont need
    water, internal
  • What does Exothermic mean? Cant maintain body
    temperature
  • Define Amniotic egg and explain the advantage.
  • How many chambers do their hearts have? 3 to 4

24
Aves (bird)
  • Examples

25
Birds
  • What are the major Characteristics?
  • Where do they live? Everywhere
  • How do they reproduce? Sexual, internal
  • What does Endothermic mean? Maintain body
    temperature
  • How many chambers do their hearts have? 4

26
Mammalia
  • Examples
  • Marsupila placental mammal monotremes

27
mammals
  • What are the major Characteristics? Endothermic,
    hair, milk glands, diaphragm, specialized teeth,
    developed brains
  • Where do they live? everywhere
  • How do they reproduce? Sexually, internal
  • How many chambers do their hearts have? 4
