Which of the following can reproduce through regeneration ?a)Hydrab)Planariac)Wall lizardd)Both (A) and (B)Correct answer is option 'D'. Can you explain this answer?

Question

Answer

Answer

Regeneration:- Organism is cut or broken into multiple pieces, each pieces give rise to new individual.
Examples:- Hydra, Planaria.

In a very simple and easiest way, as per the option d says, Hydra and Planaria can reproduce through Regeneration. Because, these organisms (Hydra and Planaria) consist specialized cell all over the body which proliferate into large number of cells, these different cell undergo changes to become various type and tissue.

Answer

Regeneration in Organisms

Regeneration is the ability of an organism to replace or regrow lost or damaged body parts. Some organisms have the remarkable ability to regenerate entire body parts. Here are the details of the organisms that can reproduce through regeneration:

Hydra
- Hydra is a small, freshwater organism belonging to the phylum Cnidaria.
- It has the ability to regenerate lost body parts, including its tentacles and body column.
- The process of regeneration in Hydra involves the proliferation of specialized cells called interstitial cells.

Planaria
- Planaria is a flatworm that inhabits freshwater environments.
- Planaria can regenerate into two separate individuals when cut in half, with each half regenerating the missing parts.
- The process of regeneration in Planaria involves the presence of pluripotent stem cells called neoblasts.

Wall Lizard
- Wall lizards, or Podarcis species, are not known for their ability to regenerate lost body parts.
- While some lizards have the capacity to regenerate their tails, the ability to regenerate varies among lizard species.

Conclusion
Both Hydra and Planaria are examples of organisms that can reproduce through regeneration. These organisms exhibit remarkable regenerative abilities that allow them to replace lost body parts and even regenerate into separate individuals. On the other hand, wall lizards do not possess the same level of regenerative capabilities as Hydra and Planaria.
