Write a short note on regeneration

Regeneration: -

i. The capacity to regenerate is very high among some animals.

ii. They can reconstruct the entire body from the isolated body cells.

Iii. Regeneration is carried out by specialized cells.

iv. These cells proliferate and make large number of cells which later developed into various cell types and tissues, and helps in production of new organism.

v. Eg. When Planaria is cut into many pieces, each piece develops into a whole Planaria. This process occurs only if the Planaria body gets cut up into pieces. But animals cannot wait to be cut to reproduce. So regeneration is not the same as reproduction.
