How are the Kingdoms Organized?
Type of cells- prokaryotic/eukaryotic
# of Cells - unicellular/multicellular
Feeding - autotrophic/heterotrophic
Cell Structure- No cell wall

What is an Autotroph?
Make their own food
What is a Heterotroph?
Do NOT make their own food

K. Animalia Characteristics
Multicellular – many cells
Heterotrophic – consume other organisms for energy
Eukaryotic – Have a nucleus
Lack cell walls – have NO cell walls
![Page 8: KINGDOM ANIMALIA Unit 2 - Biodiversity. 2 Hierarchy-Taxonomic Groups Domain Kingdom Phylum (Division – used for plants) Class Order Family.](https://reader030.fdocuments.in/reader030/viewer/2022032517/56649c805503460f949377a6/html5/thumbnails/8.jpg)
Animal Organization
K. Animalia is divided into 9 phyla based on: Level of organization
(cellular, tissue, organ system etc.)
Body symmetry (asymmetry, radial, or
bilateral) Cephalization
(concentration of sensory tissue at the head)
Body cavity formation
We will concentrate on:
Level of Organization Cellular, tissue,
organ … Body Symmetry
Radial vs bilateral vs assymetrical
Mode of Reproduction Sexual vs. Asexual
Energy Source Endothermic vs
Ectothermic
