REGERATION
REGERATION
To regrow body parts that are lost or damaged is called spicling.
yes
Regeneration is the term used to describe animals growing new replacements for lost body parts.
No.
Regeneration
The definition of a Planarian is "any of various free-swimming, mostly freshwater flatworms of the class Turbellaria, having an undulating or sluglike motion: popular in laboratory studies for the ability to regenerate lost parts." This means that it can, if any body parts are chopped off, regrow them. In junior high we sliced it's head down the middle and it regrew two heads in a matter of weeks. Cool, but really disgusting. It is a worm-like animal. The definition of animal is "any such living thing other than a human being." So in conclusion, according to the definition of animal, a Planarian is an animal, but a very strange one.
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.
A Planarian is an acoelomate, meaning they do not have a body cavity at all.
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.
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.
