PROTOZOA WORKSHEET1. Protists with animal-like characteristics are called ___________________________.2. Sarcodines use their pseudopodia for ___________________________, _____________________________, and_____________________________.3. The protozoan that causes malaria reproduces in the _______________________ ______________________ cells of humans.4. When conditions are unfavorable, many amoebas survive by becoming hard ______________. that can withstand drought,heat, or being eaten by other organisms.5. Protozoans can grow and reproduce only in _________________________________ environments6. Type of sarcodina that moves by pseudopodia is an _________________________.7. The protozoan that causes malaria reproduces in the _______________________ ______________________ cells of humans.8. The sporozoan that causes malaria is _______________________________.9. Sarcodinians are protozoans that move by extending lobes of __________________.10. ______________________________ are protozoans that move by means of flagella.11. The ciliophora that moves by cilia ________________________________.12. Some zooflagellates are free-living _____________________ or ____________________ organisms; many can live insideother organisms in _____________________ relationship.13. Zooflagellates may have a ____________________ or _____________________________ relationships with otherorganisms.14. Protozoans are all ______________________ organisms.15. One way to classify protozoans is based on the way they _______________.16. _________________ move by extending their ___________________. ____________________ propel themselves by______________________. ____________________ move by hairlike ____________, and ____________________ do _______move by themselves at all.17. The lobes of cytoplasm that sarcodinians extend are called __________________ which means "_____________________________".18. Like all ciliates, Paramecium has ______________ distinct kinds of nuclei, each with a different function. The___________________________ controls ongoing functions of the cell and __________________________ reproduction.Ciliates reproduce ________________ by cell division. The ______________________ is involved in genetic exchange during___________________ reproduction.19. Paramecium gathers food with its _____________. The ____________ sweeps food particles into the _______________________________, the Mouth _____________ opens into a ___________________ which pinches off around them to form a____________________ ______________________. It ejects wastes through an opening called the ________________________________________________.

20. Water is constantly enters the Paramecium cell by _______________________. They would burst if they did not have a wayto get rid of excess water. ______________________________ _____________________________ collect the excess water andpump it outside.21. Most protists are made up of ______________________________ cell(s).22. Most protists live in a ________________________________ environment.23. Some protists have __________________________________ that contain light sensitive pigments.24. ________________________ is a process of sexual reproduction in ciliates.TRUE OR FALSEThe kingdom Protista contains the eukaryotes that are not plants, animals, or fungi.Zooplankton protozoan species are unique among protozoa in that they are autotrophic.Conjugation is a process of sexual reproduction in ciliates.Amoebas move by means of pseudopodia.Protists cause amoebic dysentery, giardiasis, and sleeping sickness.All protozoa are parasitic during at least part of their life.The major phyla of Protists are, for the most part, closely related to each other.All Protists are unicellular.
