If the filament of Spirogyra is broken into [[1]], then each fragment will develop into a new individual Spirogyra filament.

If the filament of Spirogyra is broken into fragments, then each fragment will develop into a new individual Spirogyra filament.

Spirogyra is a genus of filamentous green algae that reproduces both sexually and asexually. One of the asexual modes of reproduction in Spirogyra is fragmentation. When the Spirogyra filament is broken into fragments due to physical stress or other factors, each fragment has the potential to develop into a new individual.

The process of fragmentation involves the breaking of the filament into smaller fragments, each containing one or a few cells. These fragments can then grow and develop into new filaments. The process is facilitated by the presence of cell walls in Spirogyra, which are made up of cellulose and provide structural support to the cells.

Under favourable conditions such as adequate light, nutrients, and water, the fragments of the Spirogyra filament can undergo rapid cell division and grow into new filaments.
