1. Characteristics of Living Things and Classification
What makes something living?
How do we organize living things?

2. How are living things organized?

3. Organization of Living Things
MULTICELLULAR
ORGANISMS
UNICELLULAR
ORGANISMS

4. 4 Characteristics of ALL Living Things
Living things are made of CELLS that contain DNA
Living things have a METABOLISM to help them use energy to live, grow, and develop
Living things maintain HOMEOSTASIS
A stable internal environment
Living things REPRODUCE

5. Characteristics of Living Things:

6. Similarities and Differences Among Living Things
Living things go about the 4 characteristics in similar AND different ways
8 Life processes that are similar and different among living things:
Obtaining nutrients
Transport of materials throughout organism
Breaking down nutrients to get energy (cellular respiration)
Combining simple substances to make more complex substances (synthesis)
Growth
Removal of waste products (Excretion)
Responding to internal and external stimuli
Reproducing

7. Simple to Complex:

8. Helping Vocabulary Number of cells: Nucleus? Mode of nutrition:
Multicellular:
Made of many cells
Unicellular:
Made of one cell
Nucleus?
Eukaryote:
Cells contain a nucleus
Prokaryote:
Cells lack a nucleus
Mode of nutrition:
Heterotroph:
Need to obtain food
Autotroph:
Can make own food

10. The Five Kingdoms:

11. The 5 Kingdoms Animalia Fungi Plantae Protista Monera
Similarities and Differences in life processes has grouped organisms into 5 different kingdoms
Animalia
Fungi
Plantae
Protista
Monera
MULTICELLULAR
EUKARYOTIC
UNICELLULAR
PROKARYOTIC

12. Obtaining Nutrients (FOOD!)
Heterotroph
Gets nutrients from the environment
Kingdoms:
Animalia, Fungi, Some Protista and Monera
Autotroph
Makes own food
Plantae and some Protists (photosynthesis), some Bacteria (chemosynthesis)

13. Transport of materials
Unicellular Orgs:
Transport within cytoplasm
Kingdoms:
Protista, Monera
Multicellular Orgs:
Transport within liquids and tubes
Animalia, Plantae, Fungi

14. Reproduction Asexual: Sexual: One parent
Offspring genetically identical (clones)
Kingdoms:
Some Fungi, Protista, Monera
Sexual:
Two parents
Offspring genetically different from parents
Some Fungi, Plantae, Animalia

15. Classification of Living Things
Why classify organisms?
For easy identification
For evolutionary comparison of organisms
Organisms are grouped into large categories based on similarities
Once in a group, organisms are separated based on differences

16. Classification of Living Things
5 Kingdoms
Phyla (s. Phylum)
Class
Order

Genus
Species

17. Acronym to help remember!

Spaghetti

18. Classification of Humans
KINGDOM: Animalia
PHYLUM: Chordata
Has backbone
CLASS: Mammalia
Females have mammary glands
ORDER: Primates
Larger brain size
FAMILY: Hominidae
GENUS: Homo
SPECIES: sapiens

19. Scientific Naming Scientific name = Genus + species
Referred to as Binomial Nomenclature (2 name naming system)
species is not capitalized
Both are always italicized or underlined
Ex. Homo sapiens or Homo sapiens
Abbreviation:
First letter of genus (capitalized), followed by species
Ex. H. sapiens
Scientists have only identified and named a FRACTION of all living organisms on Earth!!!!
