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

2. Organization of Living Things
MULTICELLULAR
ORGANISMS
UNICELLULAR
ORGANISMS

3. 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

4. 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 (Sensitivity)
Reproducing

5. Helping Vocabulary Number of cells: Nucleus- Yes or No?
Multicellular:
Made of many cells
Unicellular:
Made of one cell
Nucleus- Yes or No?
Eukaryote:
Cells contain a nucleus
Prokaryote:
Cells lack a nucleus
Mode of nutrition:
Heterotroph:
Need to obtain food
Autotroph:
Can make own food

6. Just to get you thinking!

7. (now Archebacteria and Eubacteria)
The 6 Kingdoms
Similarities and Differences in life processes has grouped orgs into 6 different kingdoms
Animalia
Fungi
Plantae
Protista
Monera
(now Archebacteria and Eubacteria)
MULTICELLULAR
EUKARYOTIC
UNICELLULAR
PROKARYOTIC

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

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

10. 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

11. 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

12. Classification of Living Things

14. 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

15. Scientific Naming Scientific name = Genus + species Abbreviation:
species is not capitalized
Always italicized or underlined
Ex. Homo sapiens or Homo sapiens
Abbreviation:
First letter of Genus, followed by species
Ex. H. sapiens
