Your four tasks to complete for this topic: (Check them off as you complete them.)

Task #1: Graphic Organizers for Protozoa and Algae

Task #2: Answer the questions from Treasure Hunt

Task #3: My Most Interesting Protist

Task #4 Respond to “The Big Question”

My Most Interesting Protist (Task #3)

From the websites listed at the beginning of this assignment and those used in the treasure hunt, cut and paste a picture (be sure it is not copyrighted) of a protist that you feel is the most interesting. Do this on a Microsoft Word document. Be sure to include your name, period and date on the paper. Include the following details:

 Picture of protist  Include the correct scientific name (genus and species, if given) of your organism  Name of the phylum to which it belongs  Describe 3 traits of this specimen  Economic and environmental impact of the protist

The Big Question (Task #4) Discuss the environmental and economic impact of members of the Protist kingdom. Support your answer using at least five specific organisms.

Do this on the back of this paper.

5 The Big Question

The Protist kingdom may include close to 60,000 species, some plant-like, some animal-like and some fungus-like. These microorganisms exist in all aquatic and terrestrial habitats. With their great numbers they have an impact on other life forms present on the Earth.

Discuss the economic and environmental/biological impact of members of the Protist kingdom on other life forms, including humans. Support your answer using details of this impact caused by at least five specific organisms.
