The protists come in two catagories. Plant-like and animal-like. I'll start with the plant-like protists. Diatoms form a hard, box-like shell around their cells. When diatoms die, their shells do not decompose but sink to the ocean floor and collect in layers, forming deposits called diatomaceous earth. Diatom shells have been mined and used in a number of ways: as the grit in toothpaste in cosmetics, as the grit in scouring powders, in highway paints (the shells reflect light very well). Red alga-seaweed! The largest protist on earth: brown alga. This is a farmer...yes, he is harvesting the alga to eat... Green alga live mainly in water environments, but can also live in soil and on trunks of trees (if the area is moist). Finally our little Euglena. Like animals, they have a means of movement (a flagellum) and a way of sensing their environment (they have an eyespot that is used to detect light).Organisms with flagella will appear to move in a “zig zag” pattern. ANIMAL-LIKE PROTISTS The amoeba The flagellates...protists with tails. All the little ciliates! And last we have the little nasties. The Sporazoans ae parasites that getinto your bloodstream, your muscles, your blood cells , your brain and make you sick... There are bazllions of protists, I hope by the end of school you have made a few friends with some of them. Get your packets down so you can use the microscopes!

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
