Question

Reproduction by means of regeneration occurs in:

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

Hint:

Planaria can regenerate an entire body from just a small fragment due to neoblast cells.

Answer 1

The Correct Option is B

Regeneration is the ability of an organism to regrow lost body parts from a fragment. Planaria, a type of flatworm, exhibits remarkable regeneration where a single piece can develop into a complete organism. This process occurs through stem cells known as neoblasts.
Incorrect options:
- Hydra (A): Reproduces mainly by budding.
- Bryophyllum (C): Reproduces through vegetative propagation.
- Pigeon (D): Reproduces sexually.
