Students will list the characteristics of protists that make them unique. CLIP A Introduction – 45 to 60 seconds Visual Audio <Image> http://commons.wikimedia.org/wiki/File:Ste ntor_roeseli_composite_image.jpg Have you ever wondered what to call those organisms that don’t quite fit into any of the obvious groups? Some life forms aren’t animals, aren’t plants, and aren’t fungi (fuhn-guy)…so what are they? <Image> Eukaryotic (you-care-ee-yaw-tick) organisms that cannot be classified as animals, plants, or fungi are in the Kingdom Protista (pro-tiss-tuh). http://commons.wikimedia.org/wiki/File:Ben thic_foraminifera.jpg <Image Display together> Protists (proh-tists) can be single-celled or simple multicellular organisms with specific internal structures. Their modes of nutrition can be either heterotrophic (het-er-oh-troe-fick) or photosynthetic.(foe-toe-sin-theh-tick) http://commons.wikimedia.org/wiki/File:Am oeba_proteus_2.jpg http://commons.wikimedia.org/wiki/File:Am oebas_from_Ehrenberg.jpg <Image Highlight the term PSEUDOPOD on image> Some protists have distinguishing features such as the use of pseudopodia (soo-doepaw-dee-uh) or “False Feet” for movement. http://commons.wikimedia.org/wiki/File:Am oeba_(PSF).png <Image Label the image “Eukaryotic Algae”> Protists are found where there is moisture. Many live in rivers, streams, oceans, and soil that is damp. http://commons.wikimedia.org/wiki/File:Diat omeas_w.jpg <Image Display images together with the title: “Red Raspberry Slime Mold”> http://commons.wikimedia.org/wiki/File:Tub ifera_ferruginosa_2010_G1.jpg http://commons.wikimedia.org/wiki/File:Tub ifera_ferruginosa-IMG_3438.jpg There are unique fungi-like protists that are heterotrophic and must seek out food, like these slime molds. <Image Display text: “Assorted Diatoms”> Diatoms (di-uh-tomes) are photosynthetic and have double shells made of silica (sillick-uh). http://commons.wikimedia.org/wiki/File:Diat oms_through_the_microscope.jpg <Image Drop in the first image, then the 2nd The algae (al-gee) are photosynthetic and image, then the 3rd image> are also multicellular. These include the red, brown and green algaes. http://commons.wikimedia.org/wiki/File:DS CN1720.JPG http://commons.wikimedia.org/wiki/File:Exp l0626_-_Flickr_-_NOAA_Photo_Library.jpg http://commons.wikimedia.org/wiki/File:Blu egreen_algae_and_mineral_deposits_in_W aimangu_Stream_(Hot_Water_Creek).jpg <Image> Ciliates (sill-ee-ates) use tiny cilia (sill-eeuh), or hair like projections for movement to seek out food. http://commons.wikimedia.org/wiki/File:Leu cophrys_patula_as_drawn_by_Stepan_Kut orga.jpg Question for Clip A Stem: Kingdom Protista is diverse and has several distinguishing characteristics. Which of the following are found in protists? Answers for Question A A. Pseudopods B. Cilia C. Photosynthetic features D. All of the above Correct Response D Correct – Go to Clip B Incorrect – Go to Clip E CLIP B <Image Place 2 arrows pointing to the extensions> Build on Introduction – 25 to 35 seconds Protists have various means of movement. Amoebas (uh-mee-buhs) move by the use of pseudopodia which are simply extensions of the cytoplasm (sie-toe-plazuhm). They are able to capture food this way too. http://commons.wikimedia.org/wiki/File:Am oeba_proteus_from_Leidy.jpg <Image> Foraminifera (four-am-in-iff-er-a) are single celled and look similar to a snail with a shell-like covering. http://commons.wikimedia.org/wiki/File:Pla nktonic_foraminifera.jpg <Image Place an arrow to flagella> Flagellates (fluh-gel-uhts) like Euglena (you-gleen-uh) and others, use a whip-like flagella to propel themselves. http://commons.wikimedia.org/wiki/File:Chl amydomonas_(10000x).jpg <Image Place the term;” CILIA” near the #8 Cilia (silly-uh) are used to propel and and highlight the perimeter of the organism control movement. Some protists, like the where cilia are located> paramecium (pair-uh-mee-see-yum) use thousands of cilia for motion. http://commons.wikimedia.org/wiki/File:Cili ophora_morphology.svg Question for Clip B Stem: Foraminifera and amoebas use _____________________________ for locomotion and to get food.

Because they conduct photosynthesis, they produce a lot of the world’s oxygen. http://commons.wikimedia.org/wiki/File:Did ymosphenia_geminata_Rio_Espolon.jpg <Image Display under image “FRESHWATER GREEN ALGAE BLOOM”> The red, green, and brown algae are multi cellular organisms that grow in fresh water and ocean colonies. http://commons.wikimedia.org/wiki/File:Wat er_blooms.JPG <Image> http://commons.wikimedia.org/wiki/File:Kel p_300.jpg Kelp beds, which are found off of the coasts, are brown algae organisms.

Flagella Correct Response A Correct – Go to Clip D Incorrect – Go to Clip G CLIP D Build on Clip C – 25 to 35 seconds Visual Audio <Image Place the term FLAGELLUM on line #1> Flagellates are marine or fresh water protists that use a whip-like tail called a flagellum (fluh-gel-um) for movement. http://commons.wikimedia.org/wiki/File:Tra chelomonas_lorica.svg <Image Place arrows pointing to the dark purple organisms> Some flagellates (fluh-gel-uhts) use hosts and can cause diseases, such as sleeping sickness in humans. http://commons.wikimedia.org/wiki/File:Try panosoma_sp._PHIL_613_lores.jpg <Image> Protists like molds are not fungi, but single-celled organisms that eat bacteria. http://commons.wikimedia.org/wiki/File:Sli me_Mold_Olympic_National_Park_North_ Fork_Sol_Duc.jpg <Image Display side by side> During environmental stress, slime molds can change their forms into a stalk that fills up and releases spores. http://commons.wikimedia.org/wiki/File:Sli me_mold_HoodRiver_Oregon.JP http://commons.wikimedia.org/wiki/File:Tric hia_decipiens_(Pers.)Macbr.jpg Question for Clip D Stem: The whip-like tail used by some protists is known as a: Answers for Question D A.

They are enclosed in a shell made of silica or calcium carbonate. http://commons.wikimedia.org/wiki/File:Cay _sand.JPG <Image> Diatoms are the major producers in the food chain and have complicated patterns and shapes. http://commons.wikimedia.org/wiki/File:Diat omeas-Haeckel.jpg <Image Place the text: “SIMILAR” above the image> Algae are similar to plants because they are photosynthetic, contain chloroplasts, and are autotrophic. http://pixabay.com/en/stinging-nettleleaves-burning-hair-474351/ <Image Place the text: “DIFFERENT” above the image> http://pixabay.com/en/leaves-nettle-greenscratchy-204375/ Algae are different from plants because they have flagella (fluh-gel-uh), and no “true” roots, stems, or leaves.

Both A & B Correct Response D Correct – Go to Clip D Incorrect – Go to Clip F CLIP H Remediation for Clip D – 25 to 35 seconds Visual Audio <Image “EXAMPLES OF FLAGELLATES> A flagellate has a whip-like appendage (uh-pen-duj) called a flagellum that it uses to move. http://commons.wikimedia.org/wiki/File:Fla gellata_1.png <Image> Flagellates can be either independent or parasitic (pair-uh-sit-ick) organisms found in animals and humans. Another distinction is that some species can be autotrophic and heterotrophic. http://commons.wikimedia.org/wiki/File:Tra chelomonas_lorica.svg <Image> Slime molds are unicellular organisms which are bright in appearance and like moist decaying soil or trees. http://commons.wikimedia.org/wiki/File:Fuli go_septica_bl1.JPG <Image> When food supplies are scarce, these organisms will group together and exist as a single being. http://commons.wikimedia.org/wiki/File:Myc etozoa_Protozo.jpg Question for Clip H Stem: Slime molds resemble fungi, but differ because of walls made of cellulose, not chitin, and the presence of a ________________ in many species.
