2. What is a characteristic of Clade Amebozoa known as lobose amoebas?

Explanation

Clade Amebozoa, specifically lobose amoebas, are known for their use of pseudopods for both feeding and locomotion. Pseudopods are temporary bulges of the cell membrane that extend and contract allowing the amoeba to move and capture food.

Submit

3. What is a defining characteristic of the Clade Amebozoa subphylum Arcellina?

Explanation

The correct answer describes the unique feature of Arcellina within the Amebozoa clade, which is the presence of a protective test surrounding the body with pseudopods extending out.

Submit

4. What type of shells do Foraminifera in the clade Cercozoa have?

Explanation

Foraminifera in the clade Cercozoa are known for having multichambered shells made of calcium carbonate (Calcareous), which sets them apart from other groups.

Submit

5. What characteristic defines a radiolarian belonging to the Clade Cercozoa?

Explanation

Radiolarians in the Clade Cercozoa are known for their actinopodia that radiate from their spherical body, aiding in movement and capturing food.

Submit

6. Clade Alveolates; Ciliate; kinetofragminophera(Didinium).

Explanation

Didinium, belonging to the Ciliate clade within Alveolates, is characterized by the absence of compound ciliary organelles, making it unique compared to other organisms within the same clade. The incorrect answers are based on features that are not typically associated with this specific organism.

Submit

7. Clade Alveolates; Ciliate; Oligohymenophora(paramecium).

Explanation

This question is asking for the classification of the organism Paramecium within the Clade Alveolates. The correct answer 'a.' indicates that Paramecium belongs to the subphylum Oligohymenophora within the class Ciliate in the Clade Alveolates.

Submit

8. Clade Alveolates; Ciliate; Oligohymenophora(Voticella).

Explanation

This question is testing knowledge of the taxonomic classification of organisms. In this case, the correct answer corresponds to the specific classification of Voticella within the taxonomic hierarchy of Alveolates. The incorrect answers have been provided as distractors to challenge the participant's understanding.

Submit

9. Clade Alveolates; Ciliate; Polyhymenophora(spirostomum).

Explanation

This question is testing the knowledge of the classification of organisms within the Alveolates clade specifically focusing on Ciliates. The correct answer 'a.' corresponds to the given classification of Polyhymenophora(spirostomum) within the Ciliate group of Alveolates.

Submit

10. Clade Alveolates; Ciliate; Polyhymenophora(Blepharisma).

Explanation

This question tests knowledge of the classification of the organism Blepharisma within the Clade Alveolates specifically in the class Ciliate. Polyhymenophora is a subclass of Ciliates, and Blepharisma is a genus within that subclass.

Submit

11. Clade Alveolates; Ciliate; Blepharisma.

Explanation

In the context of Clade Alveolates Ciliate Blepharisma, the correct answer 'line of macronucleuscytostome' refers to a specific feature of Blepharisma. This feature is involved in the functioning of the macronucleus and cytostome in the ciliate's cell structure.

Submit

12. What is the principal function of contractile vacuoles in Amoeba proteus?

Explanation

Contractile vacuoles in Amoeba proteus primarily serve the purpose of osmoregulation by regulating the concentration of salts inside the cell. This is achieved by removing excess water that enters the cell due to osmosis, helping maintain the cell's internal balance.

Submit

13. What is the function of trichocysts?

Explanation

Trichocysts are specialized organelles found in certain protozoans like Paramecium, and are used for defense mechanisms by either paralyzing or stunning prey organisms, as well as providing attachment for feeding.

Submit

14. What is the structure of Euplotes?

Explanation

The correct structure of Euplotes is that the cilia are fused into conical projections forming cirri like membranells.

Submit

15. Why do dinoflagellates have 2 grooves?

Explanation

The correct answer explains the purpose of the grooves in dinoflagellates, which is for locomotion. The incorrect answers provided do not align with the specific function of the grooves in dinoflagellates.

Submit

16. What is a pylome?

Explanation

A pylome is specifically related to the Amebozoa; arcellina group and is a structural feature that aids in feeding mechanisms.

Submit

17. Clade:Amitochondria Excavates: Diplimonads and Parabasalids.

Explanation

The correct answer describes the characteristics of organisms in the clade Amitochondria Excavates, which include Diplimonads and Parabasalids. These organisms are bilaterally symmetrical flagellates with 1 to 4 flagella, mostly parasitic, and possess several nuclei.

Submit

18. What are some characteristics of the Clade Discicristales: Euglenoids?

Explanation

The correct answer describes the typical characteristics of Euglenoids belonging to the Clade Discicristales, including the presence of one or two flagella, a few or many chloroplasts, and a stigma.

Submit

19. What is the function of a macronucleus in a cell?

Explanation

The macronucleus is primarily responsible for vegetative functions such as feeding and digestion in a cell.
