Protist Lab Name:_____________________ In this lab, you will observe a variety of living protists. Protists do not easily fit into the definitions of plant, animal, bacteria, or fungi because they are unicellular. Some of the organisms you will see will have animal-like characteristics; some will have plant-like traits, and other will have both. This is a great opportunity to see many of the organelles we have been discussing in class. If you have a smart phone or iPad use the QR reader app (available free for any device in your app store) to go directly to a YouTube of that organism. This will help you know what you are looking for. Turn your volume off! Focus on low power first. For each organism that you observe, make a drawing under the highest power you can clearly see. Use shading and colored pencils to add as much detail as you can. Try to label and identify any organelles you think you see. You are most likely to see, the nucleus, contractile vacuole, chloroplast, flagella, cilia, and cell membrane. If you see green, that means photosynthesis Chloroplast! Answer the questions about each organism. 1. Chlamydomonas Is this protist more plant like or animal like? ___________________________________ Describe the movement of this organism. ____________________________________ ____________________________________ 2. Blepharisma Is this protist more plant like or animal like? ___________________________________ Describe the movement of this organism. ____________________________________ ____________________________________ 3. Paramecium caudatum Look on pg. 501 of your book. What are the little hairlike projections all over the outside of this organism called? Compare this organism to #2. Describe some similarities and differences ___________________________________ __________________________________ What are the star shaped structures inside called (see pg. 501)?__________________ ___________________________________ 4. Amoeba proteus Watch carefully. Amoebas “ooze” forward slowly. See pg. 500.
