What are the levels of taxonomic heirarchy? - Answer Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
What are the levels of biological organization? - Answer biosphere, ecosystems,
communities, populations, organisms,
organ systems,
organs,
tissues,
cells,
atoms and molecules
Define biosphere - Answer broadest level encompassing planet earth and atmosphere
Define ecosystem - Answer system of living and non-living things in a region
i.e. grasslands, forests, tundra, desert
Define community - Answer all the collective organisms living within a biological
ecosystem
, Define populaiton - Answer a group or one particular species living within defined
boundaries of a community
Define organism - Answer the individual living members of a population
Define organ system - Answer a group of organs classified as a unit b/c of shared
functions
Define organs - Answer structures composed of two or more tissue types that perform a
common function
Define tissues - Answer a group of similar cells and the immediate environment
surrounding
Define cells - Answer living structures within organelles that function on a microscopic
level to keep an organism alive
Define atoms and molecules - Answer smallest level that function on a chemical level
What are the three domains? - Answer Eukarya, Eubacteria, Archaea
What cell type defines each domain? - Answer 1. Eubacteria and Archaea - Prokaryotic
cells
2. Eukarya- Eukaryotic cells
Which domain includes bacteria such as pyogenes? - Answer Eubacteria
Which domain is classically considered to be "extremophiles"? - Answer Archaea
What are the 4 major kingdoms of Eukarya? - Answer Fungi, Protista, Plantae, Animalia
Complete the following:
Fungi
1. Environmental adaption:
2. Growth over a lifecycle:
3. Produce new offspring:
4. Biochemical process of obtaining energy:

6. Major cell type (organization): - Answer 1. exoenzymes OR antibiotic
production/secretion
2. spore --> adult
3. asexual (budding, fragmentation, spore formation)
4. Heterotrophic
5. Metabolic processes to maintain internal humidity and metal ion balance
