Animal Kingdom Characteristics

  • Eukaryotic
  • Heterotrophic by ingestion
  • Multicellular
  • No cell walls
  • ​Motile

​Tissues

  • Eumetazoans - have true tissues
  • Body develops by gastrulation
  • 3 Tissues:
    • Endoderm
    • Ectoderm
    • Mesoderm
  • Triploblastic vs. Diploblastic

Ectoderm

Tissue covering animals

15

Mesoderm

muscle, organs

  3. ​Coelomate

17

​Acoelomate

no body cavity

18

Pseudocoelomate

hollow, false cavity

19
