DefineFirst use your Journal and Notes section of your binder to find answers.
If you can’t find the definition/ answer check your textbook.
1. Taxonomy- branch of science dealing with classifying organisms
2. Classify- to group something by characteristics
3. Binomial Nomenclature- 2 name naming system for genus and species of an organism, developed by
Carolus Linneaus
4. Domain- broadest level of classification, there are 3 Domains
5. Kingdom- 2nd broadest level of classification, there are 6 Kingdoms
6. Species- most specific classification level of an organism, also means “kind”
7. Prokaryote- cell without a nucleus, genetic information free floating
8. Eukaryote- cell with a nucleus, genetic information inside nucleus
9. Heterotroph- organism that eats other organisms for energy
10. Autotroph- organism that can make its own food
11. Multicellular- made of many cells
12. Unicellular- made of one cell
Short Answer
13. What do all living organisms have in common?
They are composed of cells
14. What is a cell?
The cell is the basic unit of life.
The basic unit of structure and function in all life.
15. All living organisms are composed of how many cells?
All living organisms are composed of one or more cells.

17. What 4 characteristics classify all organisms into one of the six Kingdoms?




Unicellular or Multicellular- one or many cells
Prokaryotic or Eukaryotic- presence of nucleus in cells
Autotrophic or Heterotrophic- how nutrients are obtained
Method of Reproduction- sexual or asexual
18. In Taxonomy, scientists give organisms a specific scientific name for each species, what is the benefit of
having a common naming system?
Scientists can communicate about experiments and theories about organisms and know that they are
discussing the same organism.
19. What is the correct format for writing the genus and species name according to Binomial nomenclature?
 First word capitalized (genus)
 Second word lowercase (species)
 Both words underlined or italicized
 Ex: Homo sapien
Prokaryotic Cells
Eukaryotic Cells
21. List some trait
unique to
each cell type




No nucleus
No or very few organelles (cell parts)
Small and simpler
Inflexible cell wall around cell




True Nucleus
Has many organelles (cell parts)
Larger and more complex
Flexible Cell membrane around cell
22. Describe
their nucleus
and genetic
material



Do not have a nucleus
Genetic material free inside cell
Genetic material is circular (kind of looks
like scribble scrabble) but is free floating,
there is no nucleus around it



Has a true nucleus
Genetic material enclosed inside nucleus
Genetic material is arranged on X shaped
chromosomes inside the nucleus
23. Describe
organelles
None
20. Draw an
example of
each type of
cell, be able
to recognize
Many membrane bound organelles

24. What are some similarities between prokaryotic and eukaryotic cells?
 Both are cells
 Both are living
 Both are microscopic
 Both contain genetic material
 Both are bound by an outer covering
 Both have cytoplasm
 Both have a metabolism for getting energy
 Both reproduce
25. List the levels of classification from broadest to most specific. Memorize. Use your Mnemonic!
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
26. What are the 3 Domains?
All living organisms are organized into three Domains: Archaea, Bacteria, and Eukarya
27. What are the 6 Kingdoms?
Archaebacteria, Eubacteria ,____ Protista, Plantae, Fungi, and Animalia ___
28. In the Domain Archaea, what are the possible Kingdoms?
Archaebacteria
29. In the Domain Bacteria, what are the possible Kingdoms?
Eubacteria
30. In the Domain Eukarya, what are the possible Kingdoms?
Protista, Plantae, Fungi, and Animalia
31. In which domain do all the Kingdoms have a nucleus?
Eukarya
Name that Kingdom
32. Multicellular, Autotrophic, Eukaryotic
33. Unicellular, Prokaryotic, can be beneficial or harmful
34. Multicellular, Heterotrophic, Eukaryotic, very diverse
35. Unicellular, Prokaryotic, ancient
