Description

Lab: Biodiversity -- Microbiology

The Scientific Method:

As you go through the lab, the scientific method will be your guide to the process. Click here for more information about the scientific method.

Introduction:

The theme of this lab is microbiology, a very broad topic that covers viruses, bacteria, archeans, and the majority of protists.

Objectives:

  1. Explore and report on a specific kingdom of “microorganisms.”
  2. Develop and present a virtual poster to be presented at your class’ online virtual presentation session.

Time Requirements:

This lab should take four hours to complete.

Recording Your Observations:

Click here to download the lab report for this lab, where you’ll record your hypotheses, observations, and conclusions.

Procedures:

  1. Visit http://www.ucmp.berkeley.edu/exhibits/historyoflife.php History of Life on Earth, University of California, Berkeley Museum of Paleontology. Click the diagram of the three domains, and then follow to the Systematics link for a group you desire to begin researching for this lab.
  2. Visit a number of websites (a few starters are listed below) that deal with the great diversity, and biological, ecological and economic impact of microorganisms to life on earth and human society. Gather (and cite!) information and images to allow you to prepare a poster or PowerPoint presentation.
  3. In your poster or PowerPoint presentation, you will need to detail the classification of the group of creatures you are detailing.
  4. Required elements include: the time of first occurrence, fossil record (if any), economic and societal impact of the group, and its evolutionary importance (for example the green algae are not terribly important save as a stem group for the evolution of plants).

Example sites:

http://www.microbeworld.org/

http://www.tolweb.org/tree/ Tree of Life Web Project. Maintained by scientists and collaborators, this site organizes over 5000 web pages about the classification and relationships of the domains and other taxonomic groups.

SYSTEMATICS FOR BACTERIA

Introduction
 Systematic refers to the study of the interrelationships

between living things, diversification of life and its

change over time.
 More than classification as it goes beyond giving names

but gives theories of mechanisms of evolution.

Time of occurrence
 Bacteria are known to have occurred first on earth

3.5 billion years ago in the Precambrian period when

the evolution of one class of bacteria known as
cyanobacteria evolved.

Fossil records
 The fossil records of the evolution of bacteria are

found in the oldest rocks indicating a record of 3.5 to

3.8 billion years ago.
 This record indicates that bacteria existed 2 billion

years before the emergence of eukaryotes.

Classes

Evolutionary importance
 Decomposition- provides carbon dioxide on earth.
 Nitrogen fixation- this gives nitrates to plants for their

growth and yield. Nitrogen-fixing bacteria include;

Rhizobium, Anabaena, Nostoc, and Spirulina.
