Bacteria

1)Use your notes to label the bacteria:2)What are pili for? Sexual Reproduction

3)What are two important ecological functions of bacteria? Nitrogen fixers, digestion, decomposers, food production

4)Which kingdom of bacteria live in extreme environments?Archaebacteria

5)What are the two ways bacteria reproduce?Binary fission ~ asexual, replicate DNA then divide into two identical daughter cells. Conjugation ~ sexual, hollow bridge formed from pili moving DNA from one cell to another.

6)Use the diagram below to answer the questions:

a)Which antibiotic worked best on the bacteria? Penicillin ~ largest zone of inhibition

b)Why was water used in

quadrant 1?Control group

Fungi

7)Most fungi are multicellular. Which are unicellular? yeasts

8)Are fungi autotrophs or heterotrophs? Heterotrophs ~ decomposers, parasites, or mutualists

9)What carbohydrate is fungi walls made of? chitin

Protists

10)Are protists considered living? Yes, they are made up of cells and carry out ALL characteristics of life

11)Some protists are unicellar. Since these organisms are simple, are they able to carry out ALL functions of life? Yes

12)What are the three types of protists?Plant-like, animal-like & fungus-like

13)Describe why each protist type above is not categorized into the other kingdoms. Do not fully fit the description or definition of plants, animals or fungus

14) Name the plant-like protist that play an essential role in marine ecosystems: phytoplankton

15)Name two reasons protists are so important. Make 70% of Earth’s oxygen, 1st link of oceanic food chain

Classification & Taxonomy

16)Why do scientists use a naming system to identify organisms?To avoid confusion of referring to an organism by its common or local name or using native languages

17)What are the 3 rules to writing scientific names?Genus capitalized, species lower case, italicized if typed or underlined if hand-written

18)What are the seven levels of the classification system?Kingdom, phylum, class, order, family, genus, species

19)Which is the broadest (biggest) category?Kingdom

a)Which is the narrowest (smallest) category?species

19) Use the classification chart below to answer the questions that follow.

b)To what phylum does the class mammalia belong?Chordata

c)What are two orders in the mammalia class?Primates, Rodentia

d)Of the four organisms, which one is most different from the others?Katydid

e)What is the scientific name of the squirrel? (Use rules from #17)Sciurus carolinensis
