Warm Up Question:

Take Cornell Notes For All The Following Info: Characteristics of Animal Kingdom Multicellular-Having or consisting of many cells or more than one cell to perform all vital functions. Eukaryotic-possessing a membrane-bound nucleus Heterotrophic-not capable of producing their own food, have to feed on organic matter for energy Cells Lack a Cell Wall-animals and most protists do not have cell walls

Animals Carry Out The Following Functions: Feeding Respiration Circulation Excretion Respond to Environment Movement Reproduction 95% off all animals are invertebrates (no back bone, example-insects)

Single Celled Ancestor First came the unicellular organism also known as a single celled organism is an organism that consists of only one cell. (Prokaryotes, most protists, and some kinds of fungi are unicellular.)

Multicellular Then came the multicellular organisms are organisms that consist of more than one cell. Most life is multicellular, as are all animals (except for specialized organisms such as Myxozoa) and land plants.

#1 Porifera: First of the Nine Phyla Phylum Name- Porifera Common Name- Sponges All the same cells.

Then came… Differentiated Cells Cells for different parts of the body, such as tissue cells to create organs.

#2 Cnidaria: Second of the Nine Phylum Pronounced-nidaria, the c is silent Have radial symmetry-These organisms resemble a pie where several cutting planes produce roughly identical pieces. Examples-Jellyfish, sea anemone

Then came… Next on the Cladogram time line is: Bilateral Symmetry-meaning that it could be divided into matching halves by drawing a line down the center.

#3 Platyhelminthes:Third of the Nine Phylum Example is a Flatworm (common name)-soft-bodied invertebrate animals Usually live inside other organisms

#4 Nematode: Fourth of the Nine Phylum Common name is Round worms-they are more advanced than flatworms but less advanced than earthworms. They have thin round bodies. Many of them are harmful, as they are parasites. Pseudocoelom - internal body cavity of some primitive invertebrates, lacking a mesodermal layer

Then came… Next on the Cladogram time line is: Coelom-a confined body cavity surrounding the internal organs

#5 Mollusca: Fifth of the Nine Phylum Examples-Shellfish, squids, snails Mollusks have a soft body (their name is derived from the Latin word mollus, meaning "soft”)

#6 Annelid:Sixth of the Nine Phylum Annelids are a large phylum of segmented worms Example- earthworms and leeches.

#7 Arthropod:Seventh of the Nine Phylum Arthropod-is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages Examples-Insects, crabs, lobsters

#8 Echinoderm: Eighth of the Nine Phylum Echinoderms are characterized by radial symmetry, several arms Examples-Sea star or starfish, sea urchins

#9 Chordate:Ninth of the Nine Phylum Chordate-are animals which are vertebrates (backbones) Animal groups in the chordate phylum include fish, amphibians, reptiles, birds and mammals.
