Detailed explanation-1: -In Spirogyra, reproduction takes place by fragmentation that involves breaking down the filaments into smaller bits.
Detailed explanation-2: -Spirogyra undergoes vegetative, asexual, and sexual reproduction. Vegetative reproduction is by fragmentation. Under favorable conditions, vegetative reproduction is the preferred mode of reproduction. The vegetative filament after fragmentation develops into a new filament.
Detailed explanation-3: -In Spirogyra asexual reproduction takes place by fragmentation. Spirogyra splits into fragments while each fragment forms an independent organism.
Detailed explanation-4: -Spirogyra reproduces asexually by fragmentation.
Detailed explanation-5: -In spirogyra, asexual reproduction takes place by fragmentation, in which the filament breaks into several pieces. Each piece grows as a new individual. The vegetative filament transforms into a new filament following fragmentation.
