Question

name any four modes of reproduction used by single organism with the help of the neat digram explain the process of regeneration in planaria ."more complex organisms can't give rise to new individuals through regeneration ". why ​

Answer 1

Answer:

Question : what are the four modes of reproduction.

Modes of Reproduction used by single organisms. 

Budding. A bud is formed which develops into tiny individual.

Fission. Fission: The parent cell divides into daughter cells.

Fragmentation.

Regeneration.

Spore Formation.

Vegetative Propagation.

Question : Explain the process of regeneration

This process is called regeneration. If the body of Planaria is somehow cut or broken up into many pieces, each piece grows into a complete organism. ... Also, regeneration does not necessarily give rise to a new individual, whereas reproduction always produces new individuals from the parent organism.

See the diagram in attachment.

Question: More complex organism can't give rise to new individual through regeneration why?

complex organism cannot give rise to new individuals through regeneration because they have complex body structure or design. they have complex tissues which further form organs followed by organ system. therefore complex organism cannot reproduce through regeneration but only through reproduction.

Hope it help u✌
