Detailed explanation-1: -Regeneration is a natural process that allows plants and animals to replace or restore damaged or missing cells, tissues, organs, and even entire body parts to full function. Scientists are studying regeneration for its potential uses in medicine, such as treating a variety of injuries and diseases.
Detailed explanation-2: -Humans can’t, but some creatures can re-grow their limbs or tails or even their brains! Sometimes, animals even cast off a part of their body on purpose. They might feel threatened, and they can re-grow it later-this is called autotomy.
Detailed explanation-3: -Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.
Detailed explanation-4: -This process of reorganization, called morphallaxis, is the most efficient way for simple organisms to regenerate. Higher animals, with more complex bodies, regenerate parts differently, usually by the production of a specialized bud, or blastema, at the site of amputation.
Detailed explanation-5: -Scientists have pinpointed gene-activating stretches of DNA that help animals to regenerate limbs, fins and other tissues. Some vertebrates can regenerate tissues after injury, but many cannot-suggesting that this trait has been lost and gained across the vertebrate family tree.
