Module 1 - SLP

Cell Structure

Overview

For your Session Long Project, SLP, you will analyze currentscientific studies related to the important events such as theDeepwater Spill.

In Modules 1-5, you will work through the results of thisstudy:

Urakawa, H., Garcia, Juan C., Barreto, Patricia D., Molina,Gabriela A., Barreto, Jose C. (2012). A sensitive crude oilbioassay indicates that oil spills potentially induce a change ofmajor nitrifying prokaryotes from the Archaea to the Bacteria.Environmental Pollution. 164:42-45

For Module 1:

  1. First read this article from Scientific American:
    Clean Up the Deepwater Horizon Oil Spill
  2. Next, define in complete sentences using a paragraphformat:
  • What is the difference between a prokaryotic and a eukaryoticcell?
  • The following terms:

Archaea

Nitrifying bacteria

Ammonia-oxidizing bacteria

Gram-negative vs gram-positive bacteria

Hydrocarbon

Bioassay

Microtox bioassay

Crude oil

Biodegradation

  1. Finally read:

    Urakawa, H., Garcia, Juan C., Barreto, Patricia D., Molina,Gabriela A., Barreto, Jose C. (2012). A sensitive crude oilbioassay indicates that oil spills potentially induce a change ofmajor nitrifying prokaryotes from the Archaea to the Bacteria.Environmental Pollution. 164:42-45
  2. Which groups of bacteria were affected differently in thisstudy?
