2Hierarchy-Taxonomic Groups DomainKingdomPhylum (Division – used for plants)ClassOrderFamilyGenusSpeciesBROADEST TAXONGenus and species are the two names used to identify specific organisms in the binomial system of classification. Division is used for plants.
3How are the Kingdoms Organized? Type of cells-prokaryotic/eukaryotic# of Cells - unicellular/multicellularFeeding - autotrophic/heterotrophicCell Structure-No cell wall
4What is a Prokaryotic Cell What is a Eukaryotic CellNo NucleusNucleus
5What is Multicellular?What is Unicellular?One cellMore than one cell
6Do NOT make their own food What is a Heterotroph?What is an Autotroph?Make their own foodDo NOT make their own food
7K. Animalia Characteristics Multicellular – many cellsHeterotrophic – consume other organisms for energyEukaryotic – Have a nucleusLack cell walls – have NO cell walls
8Animal Organization We will concentrate on: Level of 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 formationWe will concentrate on:Level of OrganizationCellular, tissue, organ …Body SymmetryRadial vs bilateral vs assymetricalMode of ReproductionSexual vs. AsexualEnergy SourceEndothermic vs Ectothermic

102 main groupsInvertebratesVertebratesNo spinal columnSpinal column
11VertebratesAnimals with a spinal cord and an endoskeleton.
12Fish Aquatic, have fins, scales and gills. Herbivores, carnivores, parasites and filter feeders.Sexual – eggs fertilized internally or externallyBilateral body symmetryEctothermic or cold bloodedFound in water
13AmphibiansTheir skin is usually smooth and lacks scales, hair, and feathers. Their skin must remain moist to aid in breathing. They lack claws on their toes.Herbivores as youth and carnivorous as adults.Sexual reproduction – eggs fertilized internally or externallyBilateral body symmetryEctothermic or cold bloodedIn water as larva and on land as adults.
14ReptilesTheir skin has scales and is dry. They have claws on their toes, teeth and lay eggs on land.Herbivores and carnivoresSexual Reproduction – eggs fertilized internally.BilateralEctothermic or cold bloodedFound in Temperate Climates
15BirdsTheir skin is covered with feathers. They have four- chambered hearts. Their bones are lightweight and usually hollow. Their forelimbs are modified as wings. They lay eggs.Herbivores and carnivoresSexual reproduction – eggs fertilized internally.Bilateral SymmetryEndothermic or warm bloodedFound everywhere.
16MammalsThey have hair, which varies greatly among species. Most have sweat glands. They have mammary (milk-secreting) glands to feed their young.Herbivores and carnivoresSexual Reproduction – fertilized internally.Bilateral body symmetryEndothermic or warm bloodedFound almost everywhere
17InvertebratesNo spinal columnSome with exoskeletons
18Porifera (poh-RIF-ur-uh) Sedentary. Body is made of cells and tissues surround by a water filled space but there is no true body cavity.filter feedersSexual & asexual (budding)Asymmetrical body symmetryEctothermic or cold bloodedLive in aquatic environments, mostly marine.
19Cnidaria (ny-Dayr-ee-uh) Are all radial in symmetry, have stinging tentacles to catch prey.carnivorous and filter feedersSexual & asexual (budding) reproductionRadial SymmetryEctothermic or cold bloodedMarine and fresh water
20Platyhelminthes (plat-ih-hel-min-theez) Most are free living and parasitic.carnivores and parasiticSexual (hermaphrodites) & asexual (fission) reproductionBilateral body symmetryEctothermic or cold bloodedMarine and fresh water
21Nematoda (nee-muh-ToHD-uh) Most are free living and parasitic.herbivores, carnivores and parasiticSexual and hermaphroditic reproductionBilateral body symmetryEctothermic or cold bloodedLive just about everywhere.
22Mollusca (mol-us-ka)Soft body and sometimes a hard shell Bodies are divided into 3 parts: Head, Foot, and Visceral Hump.filter feeders, herbivores and carnivoresBilateral symmetryEctothermic or cold bloodedMarine, fresh water and land
23Arthropoda (arth-rop-a-da) A hard outer body covering called an exoskeleton.Specialized mouth parts. Jointed legs. Compound Eyes. Segmented bodyherbivores, carnivores, ominovoresSexual (internally and externally) reproductionBilateral body symmetryEctothermic or Cold bloodedFound in aquatic and terrestrial environments
24Annelida (uh-Nel-ih-duh) Soft body worms with sections, possesses a through gut, mouth and anus.Some parasiticSexual and hermaphroditic reproductionBilateral body symmetryEctothermic or coldbloodedFound in soil and fresh water
25Echinodermata (ee-Ky-noh-durmz) Have bodies with rough skin and sharp spines, possess 5- rayed symmetry. Calcareous skeletonSexual (separate sexes) and asexual (regeneration) reproductionRadial body symmetryEctothermic or Cold bloodedFound in marine environments
