Simple breaking of mycelium resulting in formation of a new mycelium from each broken segments is called__________?
Show answer Hide answer
Answer: D. Fragmentation
Explanation
Fragmentation occurs when a mature organism physically breaks apart into multiple separate viable segments. Each broken segment possesses the biological capacity to regenerate missing tissues and grow independently. This form of asexual reproduction allows simple organisms to multiply rapidly without requiring fertilization. Asexual reproduction generates genetically identical offspring from a single parent organism without gametes. Fungi, algae, and certain invertebrates utilize fragmentation as a primary method of natural propagation. Regeneration relies on specialized undifferentiated cells capable of dividing to rebuild lost anatomical structures.
Accidental damage to fungal mycelium in soil naturally spreads the organism across new territory. Aquarium hobbyists sometimes propagate aquatic plants and invertebrates by utilizing artificial fragmentation techniques. Ecologists study asexual reproduction rates to understand how colonial organisms colonize damaged marine habitats. Sporing involves the production of specialized microscopic spores rather than large physical body breaks. Conidiation refers specifically to the formation of asexual fungal spores called conidia on hyphae. Budding involves a new organism growing as a small outgrowth from the parent cell surface.
