Animallike Protists – Review
Instructions – fill in the blanks with the correct word or words to make the sentence make sense.
1.) Most protists are ___single cellular__ while some of them contain many cells.
2.) The Amoeba belongs to the phylum ___sarcodina___.
3.) Paramecia are pretty much all the same, in that they move by cellular projections called
____cilia___.
4.) Since these organisms have no definite shape, it is difficult determining a posterior (front)
and an anterior (back). These false feet or ____pseudopods___ extend out in the direction
the organism is moving.
5.) All protists contain a nucleus and other membrane bound organelles. This type of cell is
called __eukaryotic__ because of this characteristic.
6.) Amoeba and its relatives reproduce through the process of ___binary fission___.
7.) The __contractile vacuole__ are used by the paramecium to pick up and get rid of excess
water from its body.
8.) The zoomastiginans are organisms that may infect or help several species of organisms.
African sleeping sickness is caused by the bite of the __tsetse fly__ and injects the
___trypanosoma___ organism into the host.
9.) These organisms are called zooflagellates because of the presence of one or more
___flagella__ on their body.
10.) __cilia__ are hair-like structures used by organisms to move.
11.) The phylum ___ciliophora__ is named after this characteristic. The Paramecium is the
representative organism of this group of protists.
12.) Each Paramecium contains 2 nuclei: __macronucleus__ and the __micronucleus__.
13.) Of the two nuclei the ___micronucleus___ is used during conjugation.
14.) The hard outer covering (not M&M) of the Paramecium is called the ___pellicle__.
15.) All the organisms in the phylum Sporozoa are ___parasites___.
16.) ___Plasmodia___ causes the disease malaria.
17.) In order for the malaria parasite to enter the human host, it must be placed there by a(n)
___anopheles mosquito___.
18.) Label the following picture of the Amoeba.

19.) What disease would the above organism cause if it got into the human intestine?
___amoebic dysentery (beaver fever)__.

1.) What is the independent variable? _____water temperature____.
2.) What is the mean number of amoeba in the above data? ___≈ 8__.
3.) Why do you think there is a difference in the number of amoeba and paramecium in the
same pond? ___they may feed on different prey and some are more plentiful or different
predator levels may exist and some prefer one protist to the other____.
4.) Give several viable reasons for the decline of the two types of organisms in the above data.
____water temperature is climbing, killing off prey, protists are poikolotherms (cold
blooded) and can’t function at cold temperatures, predators are thriving at higher
temperatures, or unable to reproduce at higher temperatures___.
