EVERYDAY SCIENCE

Detailed explanation-1: -The extraordinary capacity of sponges to regenerate is manifested not only by restoration of damaged or lost parts but also by complete regeneration of an adult from fragments or even single cells.

Detailed explanation-2: -Sponges are known to possess remarkable reconstitutive and regenerative abilities ranging from wound healing or body part regeneration to the impressive re-building of a functional body from dissociated cells.

Detailed explanation-3: -Sponges have a remarkable capacity to rapidly regenerate in response to wound infliction. In addition, sponges rapidly renew their filter systems (choanocytes) to maintain a healthy population of cells.

Detailed explanation-4: -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. Scientists are studying regeneration for its potential uses in medicine, such as treating a variety of injuries and diseases.

Detailed explanation-5: -Sponges are the only animals that if broken down to the level of their cells, can reassemble themselves. A sponge is passed through a sieve to break apart its cells. The cells recognize each other and reform into small new sponges.
