REGERATION
REGERATION
To regrow body parts that are lost or damaged is called spicling.

Regeneration
No.
Some organisms can regrow damaged or lost body parts like a starfish. Regeneration is the process that uses cell division to regrow body parts. Regeneration is the ability to replace damaged or missing body parts. For example, once an Elk looses its antlers, each year, they grow new ones.
A Planarian is an acoelomate, meaning they do not have a body cavity at all.
Diffusion is inadequate to move gases through the surface and into all parts of a larger animal body. However, diffusion alone is sufficient to move gases in and out of the thin body of a planarian.
The pharynx in a planarian is located on the ventral side of the body, towards the front end. It is a muscular tube-like structure that extends out of the body to help the planarian feed on prey.

Fragmentation is the ability to regrow body parts...like with a starfish, or worm. Only the worm will grow two butts, so the second half will die. But with the starfish as long as you cut through part of the nucleus (Middle) it will regrow the missing parts.
Regeneration is the process of regrowing body parts that are lost or damaged. Some animals have the ability to regenerate limbs, organs, or tissues to replace what has been lost. This process involves the growth and development of new cells to restore the lost structure.
