Question

In which type of 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.

Reproduction by fragmentationoccurs in simple multicellular organisms. For example, spirogyra. Some simple multicellular organisms like Planaria can be cut into pieces, and each piece can regenerate into a complete organism. Some complex multicellular organisms also undergo regeneration but not to reproduce. They can only regenerate parts like eyes and limbs.
