| Amaoebae move by means of false feet known as | psuedopodia |
| The usual mode of reproduction in protozoa is | asexual |
| The relationship in which two organisms of different specieis live together and neither is harmed by the association is known as | symbiosis |
| Digestion in Amoeba proteus take place in the | food vacuole |
| The Sporozoa are harmful to organisms of other species and are therefore classified as | parasites |
| Anopheles is the genus name of a | mosquito |
| The organelle that expels excess water from the protist is the | contractile vacuole |

| The number of flagella usually present in diatoms is | zero |
| Classification systems are best described as being | artificial |
| The evolution of protists involved the development of | membrane-bound organelles |
| Protists live | on land, in the sea, and in fresh water |
| The primary purpose of the protozoan cyst is to | survive unfavorable conditions |
| Trypanosoma gambiense is the organism that causes | African sleeping sickness |
| Limestone and chalk deposits are found in the shells of dead | Foraminifera |
| Plasmodium vivax is the organism that causes | malaria |
| Trichocysts in ciliates serve mainly | as defense mechanisms |
| Structures used for locomotion in the protists included all of the following except | legs |
| The best way to prevent malaria is by destroyig the breeding places of | Anopheles mosquitos |
| Paramecia move by means of | cilia |
| Flagellated gametes produced by chytrids are the | zoospores |

| The plamodium of tru slime molds is best described as | multinucleate |
| In part of the life cycle of the true slime molds, sporangia are supported by structures known as | fruiting bodies |
| During mitosis in Euglena | the nuclear membrane persists |
| The yellow-green algae lack | chlorophyll b |
| An organism that lives inside of another and does harm to its host is known as a (an) | parasite |
| Noctiluca is noted for its | bioluminescense |
| Nematocysts are used for | stinging |
| Protists are | eukaryotes |
| Chromosomes in the eukaryotes are best described as | linear |
| Protists descended from __________ evolutinary lines | diverse |
| Protozoa are unicellular | heterotrophs |
| Protozoa are classified according to methods of | locomotion |
| Trypanosoma gambiense is carried by the insect known as the ______ fly | tsetse |
| Trypanosoma gambiense is best classified as a | zooflagellate |
| Plasmodium vivax requires two hosts: _________ and human | mosquito |
| Adult sprozoans are | nonmotile |

| In Paramecium, reproductin is controlled by the ______________ | micronucleus |
| Chytrids are best classifies as | protists |
| The nuclei in the plasmodium of the true slime molds is | diploid |
| The pyrenopid body in Euglena stores | paramylum |
| The chloroplasts enable Euglena to carry out ___________- nutrition | autotrophic |
| The pigment fucoxanthin causes the _______ color in the chrysophyta | yellow |
| The diatoms have _______ commercial value | great |
| Water balance in the amoeba is conrolled by the ______ vacuole | contractile |
