3. Cellular Organization
Living things are made of building blocks called cells.
1 cell = unicellular
More than 1 cell = multi - cellular
Cells -> tissues -> organs -> organ systems
organisms
Ex: student-> 6th grade-> etc…

4. Biogenesis Life comes from life Redi’s Experiments
Pasteur’s Experiments
Spontaneous Generation – when life comes from non-living things

5. 4 Basic Needs of Life Food Water Shelter (living space)
Homeostasis (stable internal conditions)

6. Classifying Organisms
Classification is the process of grouping things based on their similarities.
Classification makes it easier for scientists to study organisms.
Taxonomy is the study of classification.

7. Taxonomy K – Kingdom P – Phylum C – Class O – Order F – Family
G – Genus
S – Species
K –
P –
C –

F –
G –
S -

8. Binomial Nomenclature
Taxonomy involves the naming of organisms.
The scientific name of any organism uses the categories genus and species.
Carolus Linneaus is the “Father of Taxonomy”
This is called binomial nomenclature (two name system)
Example – Bison bison

9. Binomial Nomenclature
Binomial nomenclature makes it easy for scientists to communicate about an organism because everyone uses the same scientific name.
Example – page 19 in textbook

10. Binomial Nomenclature
Binomial nomenclature is the two – name system used to identify organisms scientifically.
Genus species
Example – Felis leo

11. Levels of Classification
K – Kingdom
P – Phylum
C – Class
O – Order
F – Family
G – Genus
S – Species
K – Kings
P – Play
C – Chess
O – On
F – Fiber
G – Glass
S - Surfboards

12. Taxonomic Keys
A taxonomic key is a guide to help identify similar organisms.
Example – page 22 in textbook

13. Evolution & Classification
