- Euglena
- Paramecium
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand binary fission types.
Binary fission can be transverse or longitudinal depending on the plane of division.
Step 2: Identify Euglena division.
Euglena divides along its longitudinal axis, hence showing longitudinal binary fission.
Step 3: Analyze Amoeba.
Amoeba shows irregular binary fission without fixed plane.
Step 4: Analyze Paramecium.
Paramecium shows transverse binary fission.
Step 5: Biological significance.
Longitudinal fission helps maintain flagellar orientation in Euglena.
Step 6: Conclusion.
Thus, Euglena exhibits longitudinal binary fission.
Binary fission can be transverse or longitudinal depending on the plane of division.
