Kingdom Animalia pg. 406 new text Biology 11
2
Characteristics pg. 408 new text Multicellular, heterotrophic, eukaryote Most: Sexual Reproduction Aquatic and terrestrial Cell membrane No cell wall
3
Classified in various ways pg. 408 new text 1. Presence of a vertebral column 2. Body Symmetry – none, radial or bilateral 3. Body Cavity (cœlome) 4. Body layers - two or three layers 5. Body Organization – tissues, organs, organs systems 6. Digestive tract or gut – one opening or two

1. Vertebral column pg. 408 new text 2 Groups: Vertebrates (have a notocord at some stage of their life) Invertebrates (do not have a notocord) 95% of all animals are i nvertebrates ~ 30 different phylum of i nvertebrates
5
2. Body Symmetry pg. 406 new text 2 Types: Bilateral Symmetry: A shape has bilateral symmetry if one half of the shape is the mirror image of the other. Ex. humains, sharks, and ants. Radial Symmetry: A shape has radial symmetry if the shape of one part is repeated several times abut a central axis. Ex. starfish, jellyfish, sand dollar
6
2. Body Symmetry pg. 410 new text How is body symmetry related to an animal’s lifestyle and brain development? Cephalization: the concentration of nerve tissue and receptors at the anterior end of an animals body. Latin for “cephalicus”, meaning head
7
3. Body Cavities or Coelom pg. 409 new text Coelom: the fluid filled space inside the body, lined with a layer of cells called the peritoneum, it contains and protects body organs. 3 Types: Coelomates Acœlomates Pseudocoelomates
8
3. Body Cavities or Coelom pg. 409 new text Coelomates – Animals containing a true coelom lined with continuous peritoneum. Ex: Round worms, Frogs, Humans Acœlomates - Animals lacking a true coelom or body cavity. Ex: Sponges, hydra and flat worms. Pseudocoelomates - Animals containing a fluid filled space of variable shape and has no peritoneum

4. Body layers (germ layers)- pg. 408-409 new text Germ layers: layers of cells in the embryo that give rise to specific tissues in the adult. There are three different types of germ layers: Ectoderm Endoderm Mesoderm
12
4. Body layers (germ layers)- pg. 408-409 new text Ectoderm: ecto = outer and derm = skin or layer. Skin and nervous tissue. Hair and nails etc. Endoderm: endo = inner Lining of the gut Mesoderm: meso = muscle Organs of the systems
