After binary fission in Paramecium opisthe develops new:
After binary fission in Paramecium opisthe develops new:
Show Hint
Opisthe = Posterior cell develops the oral apparatus and vacuole.
Updated On: Jun 6, 2026
- Posterior contractile vacuole, oral groove, cytopharynx
- Anterior contractile vacuole, oral groove, cytopharynx
- Food vacuole, cilia, both contractile vacuoles
- Macronucleus, cilia, oral groove
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Asexual reproduction in Paramecium.
Step 2: Meaning
Morphological development in the opisthe (posterior daughter cell) during binary fission.
Step 3: Analysis
During fission, the opisthe must differentiate essential organelles that it lacks, specifically the posterior contractile vacuole, oral groove, and cytopharynx.
Step 4: Conclusion
These structures are critical for the survival of the posterior daughter cell post-fission.
Final Answer: (A)
