The ProtistsQUESTION:What are the characteristics of Kingdom Protista?MATERIALS:Amoeba (prepared slide)cover slipEuglena (prepared slide)glass slidemedicine droppermicroscopepaper towelParamecium (prepared slide)pond water samplestoothpicksPROCEDURE:1. Study the diagram of the Amoeba provided. Draw a detailed picture of theAmoeba in the Data Section labeled Amoeba. Include all of the structureslisted below in your diagram.contractile vacuolefood vacuoleectoplasmnucleusendoplasmpseudopodium2. Now get a prepared slide of Amoeba and observe it under a microscope.Carefully observe the slide at low power, medium power, and if possible athigh power.3. Make a detailed drawing of at least 3 of the Amoebas found on the preparedslide. Label all structures you observe.4. Study the diagram of the Paramecium provided. Draw a detailed picture of theParamecium in the Data Section labeled Paramecium. Include all of thestructures listed below in your diagram.anal poremacronucleusciliamicronuleuscontractile vacuolemouth porefood vacuoleoral groove5. Now get a prepared slide of Paramecium and observe it under a microscope.Carefully observe the slide at low power, medium power, and if possible athigh power.6. Make a detailed drawing of at least 3 of the Paramecium found on theprepared slide. Label all structures you observe.7. Study the diagram of the Euglena provided. Draw a detailed picture of theEuglena in the Data Section labeled Euglena. Include all of the structureslisted below in your diagram.chloroplastnucleuscontractile vacuole paramylon bodyeyespotpellicleflagellumreservoir8. Now get a prepared slide of Euglena and observe it under a microscope.Carefully observe the slide at low power, medium power, and if possible athigh power.9. Make a detailed drawing of at least 3 of the Euglena found on the preparedslide. Label all the structures you observe.

10. Make up a wet mount slide of one of the pond water samples provided.Carefully observe the slide at low power and medium power. Try to find atleast 3 different protists in the sample. In the Data Section labeled PondProtists, make a detailed diagram of each protist you find and identify thephyla to which it belongs.11. Make up a wet mount slide of one of samples containing algae. Carefullyobserve the slide at low power and medium power. Find at least two differentalgae samples and observe them carefully. Make a detailed drawing of eachalgae specimen in the Data Section labeled Algae Samples.DATA: AmoebaAmoeba DiagramPrepared AmoebaParameciumParamecium DiagramPrepared Paramecium
