Kingdom Animalia pg. 406 new text
Biology 11
Characteristics pg. 408 new text
Multicellular, heterotrophic, eukaryoteMost: Sexual ReproductionAquatic and terrestrial Cell membraneNo cell wall
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 layers5. Body Organization – tissues, organs,
organs systems6. 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 invertebrates~ 30 different phylum of invertebrates
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
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
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
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
A coelomate
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
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
Coelomates
