1. UNIT 1 PART 2: CLASSIFICATION OF LIVING THINGS
All living things are put into groups, or classified. They are organized.
This makes them easier to study and easier to find.
The branch of biology that deals with classifying and naming organisms is called taxonomy.

2. Binomial Nomenclature
---2 name naming system
Developed by
Linnaeus
Genus species
Ex: Homo sapien
The classification system also can show evolutionary patterns
---what species is related to another species

4. 7 Major Groups for classification
Kingdom
Phylum
Class
Order
Family
Genus
Species Only one type of organism is in a species.
King Phillip Came Over For Group Scuba

5. Each kind of organism has a two word Latin name made up of its genus and species names. This is its scientific name and is always written in italics.
Kingdom
Animal
Phylum
Chordate
Class
Mammal
Order
Carnivora
Primate
Family
Canine
Felidae
Homidae
Genus
Canus
Felis
Homo
species
familiarus
lupis
domesticus
sapiens
Common
Dog
Wolf
Cat
Human
The scientific name of a human is Homo sapiens.

6. The Five Kingdoms 1.) Monerans ---EX: Bacteria unicellular
no organelles---prokaryotic
asexual reproduction
heterotrophic
--can’t make food— must get it from others
earliest life forms

8. The Five Kingdoms 2.) Protist unicellular have organelles---Eukaryotic
asexual reproduction (some sexual )
some are animal-like, some are plant-like, and some are both
EX: Ameba, paramecium, euglena

9. paramecium
euglena
diatoms

10. The Five Kingdoms 3.) Fungi multicellular ---mushroom
unicellular---yeast
Heterotrophic
asexual
Eukaryotic
No chlorophyll so no photosynthesis. They do not make their own food.

11. The Five Kingdoms 4.) Plants Autotrophic----makes its own food
unicellular—algae
multicellular---trees, grass
asexual and sexual
Contains chlorophyll
Multicellular, cells have cell walls

12. The Five Kingdoms Animal
Mammals, insects, birds, sponges
Can move on their own
Multicellular, cells do not have cell walls
Eukaryotic
Must get food from the environment

13. Taxonomic Keys A tool used to identify organisms already classified.
Most are dichotomous. That is, there are only two choices at each step that describe some characteristic of the organism.

14. Using the characteristics shown above, please make a dichotomous key for the 13 triangular critters at the left. Some characteristics may be used more than once. You may use their assigned numbers for names.
