Question 1

It is a vast group with a variety of multicellular animals in different forms.

Answer 1

Kingdom Animalia

Question 2

The members of this kingdom are called ___________, which are single- celled or colonial eukaryotes.

Answer 2

Protists/Protozoans

Question 3

All protozoans fall under one kingdom.

Answer 3

Kingdom Protista

Question 4

General Characteristics of __________.
• single celled organisms, some colonial
• no cell wall but some secrete a “shell” of silica or calcium carbonate or a flexible pellicle
• mostly heterotrophs (obtains organic molecules from other organisms through ingesting their
food)
• move by flagella, cilia, pseudopodia, or are non-motile
• inhabit a diverse array of habitats and include freshwater and marine
forms to soil dwelling, symbiotic and parasitic forms.

Answer 4

animal-like protists (Protozoa)

Question 5

4 major Phylas that are important to zoology:

Answer 5

• Phylum Sarcomastigophora
• Ciliophora
• Apicomplexa
• Dinoflagellata

Question 6

Structures that aid in their locomotion:

Answer 6

•Flagellum (plural: Flagella)
• Cilia
• Pseudopodia
• Cytosome
• Apical Complex
• Macronucleus and Micronucleus
•

Question 7

A long contractile fiber, arising from a basal body. May be single or several

Answer 7

Flagellum (Plural: flagella)

Question 8

Short fine hair made of contractile fiber arising from the basal body and covers much of the body surface and beat in unison to effect movement.

Answer 8

Cilia

Question 9

Prolongations of cytoplasm

Answer 9

Pseudopodia

Question 10

Pseudopodia means:

Answer 10

(“pseudo”fake + “pod” feet)

Question 11

Examples of pseudopodia:

Answer 11

Volvox

Question 12

The “mouth” or “gullet” of most protozoans in the Phylum Ciliophora

Answer 12

Cytosome

Question 13

A structure present only in members of Phylum Apicomplexa.

Answer 13

Apical Complex

Question 14

Members of Phylum Ciliophora have 2 types of nuclei.

Answer 14

Macronucleus
and Micronucleus

Question 15

Large nuclei “macro= big) which contain most of the DNA that controls the metabolic activities of the organism.

Answer 15

Macronucleus

Question 16

Smaller nuclei (“micro” =small) which stores a small amount of DNA that is used only for the exchange of genetic material during sexual reproduction.

Answer 16

Micronucleus

Question 17

Classification of Major Phyla of Animal-like Protists:

Answer 17

Phylum SARCOMASTIGOPHORA
Phylum APICOMPLEXA
Phylum CILIOPHORA

Answer 18

Phylum SARCOMASTIGOPHORA

Question 19

Phylum SARCOMASTIGOPHORA divided into 2 subphylums:

Answer 19

• Subphylum SARCODINA
•Subphylum MASTIGOPHORA

Question 20

Members are called amoebas and move/catch food using pseudopods.

Answer 20

Subphylum SARCODINA

Question 21

Members are called flagellates because they possess 1 or more flagella

Answer 21

Subphylum MASTIGOPHORA

Question 22

Members are obligated intracellular parasites (need to enter the cells of a host in order to reproduce)

Answer 22

Phylum APICOMPLEXA

Characterized with having an apical complex found in certain stages in their life.

Answer 23

Phylum APICOMPLEXA

Question 24

Members are called ciliates because they possess cilia.

Answer 24

Phylum CILIOPHORA

Question 25
