11
Taxonomy Study of classifying things Why? – Organization – Identification – Show relationship between organisms Linnaeus (1707-1778) – Father of nomenclature
12
Classification Hierarchy (page 475) 1.Kingdom 2.Phylum 3.Class 4.Order 5.Family 6.Genus 7.Species
13
Binomial nomenclature How to name an organism in the animal kingdom Example: – Homo sapien (genus) (species) -generic -specific 1.Species lower case, genus capital first letter 2.Always written in italics or underlined individually 3.Nomenclature is derived from Latin
14
Animal Kingdom Chapter 32 (pg. 589-597) Characteristics 1.Vertebrate or Invertebrate 2.Multicellular 3.Heterotrophic 4.Lack cell wall 5.Sexual reproduction (sperm and egg) 6.Unique tissue type for movement a. Nervous b. Muscle 7. Embryo Development—differentiation of cells (pg 589-590)
15
What is an animal (cont’d) 8. Symmetry—arrangement of body parts around a central point a. Asymmetry-no definite symmetry b. Radial symmetry-divided in to halves by any plane that passes through its longitudinal axis Example: starfish, jellyfish
16
What is an animal (cont’d) c. Bilateral symmetry-divided into halves; left and right are mirror images of each other Example: human Dorsal-topAnterior-head Ventral-bottomPosterior-tail
17
Symmetry
18
What is an animal (cont’d) 9. Cephalization (associated with bilateral symmetry) -evolutionary trend whereby nervous tissue becomes concentrated toward one end of an organism -a head with a sensory organ associated with bilateral symmetry (humans)
19
What is an animal (cont’d) 10. Embryo Development (bilaterals) -embryo becomes layered during development called germ layers that form concentric layers of various tissues and organs 1. Ectoderm-covering of embryo-becomes skin 2. Endoderm-innermost-becomes digestive 3. Mesoderm-middle-forms muscle and other linings
20
What is an animal (cont’d) 11. Coelum (found in coelomates) (pg. 593) -fluid filled body cavity lined with mesoderm -suspend the internal organs -functions to cushion organs, prevent internal injury, enabled organs to grow and move
21
Phylums of Animal Kingdom 1.Porifera: (sponges) -hollow tube -no brain -radial or asymmetry -takes in food via water through pores
22
Phylums of Animal Kingdom 2. Cnidaria (sea anemone, coral, jellyfish) -marine environment -radial symmetry -single body cavity -reproduce sexually
23
Phylums of Animal Kingdom 3. Platyhelminthes (tapeworm, planarian, fluke) -bilateral symmetry -unsegmented -no body cavity -no respiratory/circulatory organs -flat shape -parasitic groups
24
Phylums of Animal Kingdoms 4. Annelida (earthworm, leeches) -segmented -has digestive system -simple brain -5 hearts -takes in oxygen through skin -has both sperm/egg in body -bilateral symmetry
25
Phylums of Animal Kingdom 5. Arthropoda (insects, crustaceans) -jointed limbs -made of chitin -hard outer covering -segmented body -lay eggs
26
Phylums of Animal Kingdom 6. Echinodermata (sand dollar, sea star, sea urchin) -marine animal -radial symmetry -no external skeleton -skin of mesoderm covers endoskeleton -digestive tube (mouth to anus)
27
Phylums of Animal Kingdom 7. Chordata (vertebrates) -skeleton -ingest food by mouth -brain and nervous system -warm or cold blooded -lungs or gills -sexual reproduction -bilateral symmetry
28
Chordata Classes of the phylum (page 599) 1.Agnatha (jawless fish) 2.Chondrichthyes (cartilaginous fish) 3.Osteichthyes (bony fish) 4.Amphibians 5.Reptiles 6.Birds 7.Mammals
