Write 1 similarity and diffrence of fragmentation and Gemma formation
Answers
Answer:
Regeneration is termed as an asexual mode of reproduction. It is common in unicellular organisms and lower multicellular organisms, such as planaria. Here, the organism fragments when it’s ready to reproduce, and new organisms are regenerated from these fragmented parts. The difference between regeneration and fragmentation are summarized below:
Difference Between Fragmentation and Regeneration
Fragmentation Regeneration
Organisms that are fragmented result in each fragment growing into an individual organism Regeneration occurs when an organism only regrows a lost limb or any other part of the body.
A new individual emerges from each fragment No new organisms are formed
Only a few organisms can fragment and form new individuals All organisms exhibit the ability to regenerate (Only to some degree)
Fragmentation is observed in organisms such as flatworms and sponges Examples of regeneration include regrowing a lost limb, such as the tail of a lizard. (Please note: Most lizards can lose their tails and then have them grow back. But if they lose their forelimb or hindlimb, it will not regrow)
Conclusion:
Fragmentation is a method of asexual reproduction where an organism reproduces by the process of splitting into fragments and each fragment grows into an individual organism. Regeneration, on the other hand, happens when an organism regrows certain parts or limbs which is lost due to predation.
Points to Ponder:
In most cases, fragmentation happens when an organism wants to reproduce, so after the organism splits, a process called true regeneration enables the creation of new individuals from the fragments. On the other hand, regeneration in other animals does not mean the creation of new individuals, but just regrowing lost limbs. So technically, is regeneration a form of asexual reproduction? The answer to that is both “Yes” and “No.”
Answer:
Difference between Fragmentation and Regeneration
Parameter Fragmentation Regeneration
Description Organisms that undergo fragmentation result in each part or fragment growing into another individual organism It happens when an organism regrows a lost part of the body like a lost limb
New Organism Emergence of a new individual takes place from each fragment Formation of no new organism happens here
Prevalence Fragmentation happens in only a few organisms Each and every organism can exhibit the phenomenon of regeneration
Example of Fragmentation and Regeneration Fragmentation happens in organisms like sponges and flatworms Examples of regeneration can include the tail of a lizard and regrowing a lost limb
