Question

Which of the following organisms exhibit regeneration?

• A. Planaria
• B. Homo sapiens
• C. Pavo cristatus
• D. Naja naja

Hint:

Regeneration Examples.

• High: Planaria, Hydra, Starfish.
• Limited: Humans (wounds), lizards (tails).

Answer 1

The Correct Option is A

Planaria are flatworms known for remarkable regeneration. Even small fragments can regrow into complete organisms. Humans, peacocks, and cobras have very limited or no such ability.

Answer 2

The organism that exhibits regeneration is Planaria.
Regeneration is the remarkable ability of an organism to regrow lost or damaged parts of its body.
Planaria, a type of flatworm, is well-known for its extraordinary regenerative capabilities.
If a planaria is cut into pieces, each piece can regenerate into a complete new organism.
This ability is due to the presence of a large number of pluripotent stem cells called neoblasts, which can differentiate into various cell types.
Regeneration in planaria is an important subject of study in developmental biology and regenerative medicine.
It provides insights into cellular processes like differentiation, growth, and tissue repair.
Understanding regeneration in planaria helps researchers explore possibilities of tissue regeneration in higher organisms, including humans.
Thus, planaria serves as a valuable model organism for studying regeneration.
