Question

Planaria possesses high capacity of:        [2014]a)Metamorphosisb)Regenerationc)Alternation of generationd)BioluminescenceCorrect answer is option 'B'. Can you explain this answer?

Answer

Regeneration capacity of Planaria:
Planaria is a flatworm that has the remarkable ability to regenerate its lost body parts. This capacity makes planaria an ideal model organism for studying regeneration. Here are some of the ways in which planaria exhibit high regeneration capacity:

Complete regeneration of the entire organism: Planaria can regenerate the entire organism from a small piece of the body. Even if the worm is cut into many small pieces, each piece has the potential to regenerate the entire organism.

Regeneration of missing body parts: Planaria can regenerate any missing body part, including the head, tail, and internal organs. This regeneration process is rapid and can occur within a few days.

Ability to regenerate from pluripotent stem cells: Planaria possess pluripotent stem cells that can differentiate into any type of cell. These stem cells are responsible for the regeneration of missing body parts.

This high regeneration capacity of planaria is due to the presence of a specialized population of cells called neoblasts. These cells are responsible for the continuous growth and maintenance of the planarian body. When a body part is lost, neoblasts migrate to the site of injury and differentiate into the required cell types to regenerate the missing body part.

In conclusion, the high regeneration capacity of planaria makes it an ideal organism for studying regeneration and could potentially lead to new therapies for tissue repair and regeneration in humans.

Answer

Planaria is immortal untill its genetic material is being crushed after crushing its genetic material it losses capacity of regeneration.

Answer

Correct option is (B).Planaria
because, under a certain condition, planaria breaks his body in two-three parts.And from each part new individual planaria regenerate.
Hence, this reproduction is known as Regeneration.
So, (B) planeria is a right answer.

Answer

If we cut planaria to little parts it will regenerate  from lost parts.flatworm is an eg: for it.

Answer

Moreover, planaria are mortal or do not die unless they are crushed. As they regenerate their lost part.
