1. Classification
ZOOLOGY

2. The science of classifying organisms is called taxonomy
The “father of modern taxonomy” was Carolus Linnaeus
The science of classifying organisms is called taxonomy
The “father of modern taxonomy” was Carolus Linnaeus (Carl von Linné)
Organisms are grouped into “taxa” based on their similarities to each other

3. The Old System 5 Kingdom Classification System:
Monera: all prokaryotes
Protista: single-celled eukaryotes (protists)
Fungi: multi-cellular heterotrophic sessile eukaryotes
Plantae: multi-cellular autotrophic sessile eukaryotes
Animalia: multi-cellular heterotrophic motile eukaryotes

4. 6 Kingdom Proposal Archebacteria EUbacteria
6 Kingdom Classification System
Kingdom Eubacteria: true bacteria
(formerly in kingdom monera)
Kingdom Archebacteria: extremophiles (formerly in kingdom monera)
Kingdom Protista (same)
Kingdom Fungi
Kingdom Plantae
Kingdom Animalia

5. Organisms are grouped into smaller and smaller groups all the way down to their species
A species is the most specific grouping and includes only organisms that can interbreed with each other and produce fertile offspring

6. Prokaryotic Cell

7. Eukaryotic Cell

8. 3 Domain System:
Archaea: prokaryotes; extremophiles
Eubacteria: prokaryotes; true bacteria
Eukarya: eukaryotes
Protista
Fungi
Plantae
Animalia

Taxa

10. Ursus americanus American Black Bear Binomial Nomenclature:
“a two-name system”
First part of name: Genus first letter always capitalized
Second part : species
first letter always lowercase
Binomial Nomenclature: “a two-name system”
First part of name: genus first letter always capitalized
Second part of name: species first letter always lowercase
Entire name is underlined and italicized
Names must be submitted for acceptance by original discoverer, and are generally Latin or Latinized
Ursus americanus
American Black Bear

11. Canis domesticus Canis lupus
Often Latin names contain clues about the type of organism being described.
Canis domesticus
And closely related organisms are often in the same genus, also giving clues about their names
Canis lupus
Some names are given after the discoverer, or the discovery location, or even a Latinized descriptive term in English

12. Autotrophs capture the light energy from sunlight and convert it to chemical energy they use for food.
Heterotrophs must get energy by eating
autotrophs or other heterotrophs.
Decomposers (aka saprobes) are heterotrophs that recycle dead organisms by breaking them down. Fungi are decomposers.

13. ~ Body Plans of Animals~
An animal shows assymetry if there is no central axis (some sponges)
An animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. (jellyfish, sea anemone)
An animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other. (eel, bird, fox)

14. Which figure has bilateral symmetry? Which has radial symmetry?

15. Anatomical Terms for Animals

17. Domain Archaea Formerly part of the kingdom monera
Microbiologists who study bacteria determined that the DNA of these are much different from other, true bacteria
Most Archaea live in extreme conditions (very hot, acidic/basic, sulfurous, etc)

18. Domain Eubacteria Formerly a part of the kingdom monera
Name means “true bacteria”
These are the kind of bacteria likely to make us sick, live in our gut to help us digest food, or be used in the making of cheese
Bacilli
Streptococcus
Staphylococcus
Dicoccus
Spirilla

19. Domain Eukarya
Contains all of the eukaryotes (organisms with a nucleus in their cells)
Protista
Fungi
Plantae
Animalia

21. Kingdom Fungi
All eukaryotic, multicellular, heterotrophic, sessile organisms.
Includes: molds, mushrooms, rusts, and lichens.
All eukaryotic, multicellular, heterotrophic, sessile organisms
Includes: molds, mushrooms, rusts, lichens
Mycorrhizal associations allow plants to absorb more water and nutrients from the soil

22. Coniferophytes (Pine Trees)
Kingdom Plantae
