Question

Example of regeneration is —

• A. Hydra
• B. Bryophyllum
• C. Amoeba
• D. Planaria

Hint:

Regeneration is seen in simple multicellular organisms like Planaria and Hydra, but it’s most prominent in Planaria.

Answer 1

The Correct Option is D

Step 1: Understanding regeneration.
Regeneration is the biological process through which an organism restores or regrows lost body parts. It involves the division and differentiation of specialized cells.
Step 2: Examples.
- Hydra reproduces by budding, not regeneration.
- Bryophyllum reproduces by vegetative propagation.
- Amoeba reproduces by binary fission.
- Planaria can regenerate its entire body from small fragments, showing true regeneration.
Step 3: Conclusion.
Hence, the best example of regeneration is Planaria.
