Question
Which one of the two multicellular organisms Spirogyra and Planariareproduces by regeneration and why ? Give an example of any otherorganism which can also reproduce by the same process.
Solution
Among the two multicellular organisms, Spirogyra and Planaria, it is Planaria that reproduces by the process of regeneration.
Regeneration is a type of asexual reproduction where an organism regrows its lost body parts. In Planaria, when the body is cut or split into pieces, each piece can grow into a new organism. This is possible because of the presence of a large number of totipotent cells, which have the ability to grow into any type of cell.
Another organism that can reproduce by the same process is the starfish. If a starfish loses an arm, it can grow a new one. In some cases, an entire starfish can grow from a single lost arm.
