In which process multicellular organisms break into smaller pieces upon maturation?

Correct option is D

Correct Answer: (D) Fragmentation

Explanation: In fragmentation, a multicellular organism breaks into smaller pieces upon maturation, and each fragment has the potential to grow into a complete organism. This process is common in some plants and simple animals like starfish and certain types of worms.

Other options :

• Sporulation: This involves the formation of spores, which can develop into new individuals, but it does not involve breaking the organism into pieces.
• Fission: Fission is the process where an organism divides into two or more parts, each becoming a new individual. This is more common in unicellular organisms, not multicellular ones.
• Regeneration: Regeneration is the process where parts of an organism are regrown after injury, but it does not involve breaking the organism into pieces initially.
