Question

In which of the organisms is fragmentation and/or regeneration a mode of reproduction?

• A. Complex multicellular plants and animals
• B. Complex unicellular organisms
• C. Simple multicellular plants and animals
• D. Simple unicellular organisms

Answer 1

The correct option is C

Simple multicellular plants and animals

Fragmentation and/or regeneration primarilyoccurs in simple multicellular organisms as a mode of reproduction. Although regeneration can occur in fully differentiated multicellular/complex organisms as well, it can only regenerate a part of the organism. Higher form of multicellular organisms are too complex for reproduction by these types of processes.
Fragmentation is seen in many organisms such as cyanobacteria, molds, lichens, etc. Regeneration is seen in planaria and even starfish.
