Difference Between Fragmentation and Regeneration

Thekey differencebetween fragmentation and regeneration is thatfragmentation is the process of breaking an organism into several pieces that are capable of growing into new individuals while regeneration is a form of re-growth of a broken part of the body。

There are two types of reproduction methods seen in all the organisms living on this earth. They areasexual reproduction and sexual reproduction。无性繁殖不涉及遗传材料的交换，而性繁殖涉及遗传物质的交换。由于无性繁殖中没有遗传材料交换，因此变异的可能性非常低。但是，无性繁殖在适应恒定环境的情况下更有优势，没有显着变化。在动物中，无性繁殖通常在无脊椎动物forms. There are different types of asexual reproduction methods such asfission,budding, fragmentation and regeneration. Mainly, this article attempts to discuss the difference between fragmentation and regeneration.

What is Fragmentation?

Fragmentation is the process of breaking off a piece of an organism followed by mitotic cell division. It is a mode of asexual reproduction which does not involve meiosis. Further, this broken part can develop into an independent adult. Reproduction of sea anemones, starfishes, and flatworms are well-known examples of fragmentation.

片段化是无脊椎动物中繁殖的一种非常常见的模式，并且在脊椎动物中不存在。蓝细菌，霉菌，地衣，许多动植物等生物体，例如海绵，扁虫和海星等碎裂以繁殖。碎片化的能力取决于生物体的复杂性。它可能是有意的，也可能是自然而然地发生的，也可能是由掠食者发生的。在大多数情况下，在分裂之后，两个片段都能够再生为完整的个体。

What is Regeneration?

再生是一种修改的碎片形式。这是一种使基因，细胞，器官，生物和生态系统在干扰或损害后具有弹性的过程。每个生活在地球上的物种都可以再生，但是只有少数物种将其用作无性繁殖方法，并使用其身体部位产生新个体。

Planarian flatworms possess high regeneration capabilities compared to other organisms. Among vertebrates, tailed amphibian (Salamanders and newts) and certain lizards (geckos) are capable of regenerating their limbs, tails, jaws, eyes and certain internal organs. As they are more complex multicellular animals, they cannot use regeneration to reproduce or as an asexual reproduction method. Starfishes also have the same ability to regenerate their arm, but unlike tailed amphibians and lizards, lost arms of starfishes could regenerate a completely new organism.

There are two major steps in the regeneration process. Firstly adult cells de-differentiate into stem cells. Stem cells are similar to embryonic cells. These stem cells then develop and differentiate into new tissues, thereby making new parts.

分裂和再生之间有什么相似之处？

• Fragmentation and regeneration are two methods which help living organisms to grow their bodies.
• Both methods occur mainly in multicellular organisms.
• 同样，这两个过程都是有丝分裂的。

What is the Difference Between Fragmentation and Regeneration?

碎片化是将生物体分解成几个能够成长为新个体的过程的过程，而再生是身体破裂的重生。因此，这是分散和再生之间的关键区别。此外，只能以无脊椎动物形式看到碎裂，而脊椎动物和无脊椎动物都存在再生。因此，我们可以将其视为破碎和再生之间的主要区别。

此外，碎片化是一种繁殖方法，而再生可以用作繁殖方法（例如海星）或再生损坏或失去的身体部位（例如蜥蜴）。此外，分裂和再生之间的另一个差异是，在动物中，再生比在植物中更常见，而在植物中比动物（例如非血管植物）更常见。另外，只有在某些生物体中才能找到碎裂，而在地球上几乎所有的动物中都可以找到各种形式的再生。

概括– Fragmentation vs Regeneration

Fragmentation is a method of asexual reproduction. In this method, an organism divides into several parts which are capable of developing into new organisms. Regeneration is the process that aids in the re-growth of broken parts of an organism. Some organisms use regeneration as a mode of reproduction as well. Generally, fragmentation is common in invertebrates, while regeneration is common to all living organisms. Thus, this is the summary of the difference between fragmentation and regeneration.
