Fragmentation in Spirogyra
In Spirogyra, the filamentous thallus is broken into multiple fragments by the dissolution of the middle lamella between cells which will undergo multiple mitotic divisions that will give rise to new filaments that will mature to form adult filaments.
What is Fragmentation?
Fragmentation is a form of asexual reproduction in which the organism’s body breaks into pieces that further develop into new organisms that develop and mature to show the same process of reproduction. In this process, the organism may break into two or more fragments that will grow into a complete clone. This process is usually seen in favorable conditions with ambient conditions and nutrient availability.
