Pseudopodia in Actinophrys are of this type:
Show Hint
- Lobopodia
- Filopodia
- Reticulopodia
- Helioipodia
The Correct Option is D
Approach Solution - 1
To solve the problem, we need to identify the type of pseudopodia in Actinophrys.
1. Understanding Pseudopodia in Actinophrys:
Actinophrys, a type of protozoan, uses pseudopodia for movement and feeding. Pseudopodia are temporary projections of the cell's cytoplasm used for locomotion and capturing food.
2. Analyzing the Options:
(1) Lobopodia: These are blunt, finger-like extensions of the cytoplasm, which are typically seen in amoeba-like organisms, but not characteristic of Actinophrys.
(2) Filopodia: These are thin, thread-like extensions of the cytoplasm and are more characteristic of certain amoebas, but not typically Actinophrys.
(3) Reticulopodia: These are networks of interconnected pseudopodia, seen in some amoeba-like organisms. While Actinophrys does have branching projections, this type is not the correct answer.
(4) Heliopodia: These are star-shaped projections, which is the correct type of pseudopodia found in Actinophrys.
3. Identifying the Correct Answer:
The correct type of pseudopodia in Actinophrys is heliopodia, which are radiating projections that form a star-like shape.
Final Answer:
The correct answer is Option D: Heliopodia.
Approach Solution -2
Actinophrys, commonly known as sun animalcules, are a genus of free-living unicellular protists characterized by their radial symmetry and stiff, radiating pseudopodia called helioipodia. These structures are not only used for movement but also play a critical role in capturing and engulfing prey through a process known as phagocytosis.
