Question #46939
The Question
The mycelium of Phycomycetes (e.g., Rhizopus) is characterized by an aseptate and coenocytic condition. Which of the following statements regarding this cellular organization and its biological parallels is INCORRECT?
Options
- A.
The coenocytic state arises due to repeated karyokinesis that is uncoupled from subsequent cytokinesis.
- B.
This continuous multinucleate protoplasmic mass is structurally analogous to the syncytial condition found in human smooth muscle fibers.
- C.
Members of this class, such as the parasitic fungus Albugo on mustard, obligately exhibit this lack of septation in their vegetative phase.
- D.
This condition challenges the classical cell theory by functioning as a continuous, multinucleated unit rather than discrete uninucleate cells.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: The question bridges Kingdom Fungi (Biological Classification) with Human Histology (Structural Organization).
The trap relies on 'Functional Overlap' and 'Location Specificity'—students often memorize that 'muscles are syncytial' but fail to distinguish that this applies strictly to skeletal muscles, whereas smooth and cardiac muscles are uninucleate.
