Kingdom Protista

Unicellular and multicellular eukaryotes Might live in a colony or groups Some are photosynthetic, others ingest food while others absorb their food. Some move (flagella, cilia, pseudopods) other are stationary. Reproduce sexually and asexually Main Characteristics

Alteration of Generations Two distinct phases –Diploid, spore- producing phase (asexual) –Haploid, gamete producing phase (sexual)

A. Protists lacking Mitochondria Ex. Giardia, trichomonas

Euglena B. Protists with Flagella

Spongomonas is a colony of flagellates living in a gelatinous matrix. they use their flagella to gather food.

Protists with Flagella (con’t) Trypanosoma – African Sleeping Sickness Tsetse fly vector

C. Protists with Cilia Cilia

Protists with Cilia Plasmodium – malaria Anopheles mosquito vector

Malaria control As the globe warms up, the areas with malaria are growing. Countries with malaria use DDT to control mosquitoes (banned in the US – biological magnification) Researchers are introducing an inhibition gene into some of the mosquitoes and releasing them into the wild to pass on that gene.

D. Golden and Brown Algae The term 'algae' is used for some lower plants and many, often unrelated groups of microorganisms that are able to perform photosynthesis. Kelp

E. Red Algae No flagella

F. Green Algae

Chlamydomonas unicellular green alga swims with two flagella, and has chloroplasts for photosynthesis. Chlamydomonas has nothing to do with Chlamydia, by the way.

Spirogyra

G. Protists with Pseudopods

H. Slime Molds heterotrophic
