Question

Spirogyra reproduces asexually by _________.

Options

• Binary fission

• Budding

• Fragmentation

• Gemmule formation

Answer 1

Spirogyra reproduces asexually by fragmentation.

Explanation:

Spirogyra is a filamentous green alga that reproduces by fragmentation. Its long filament breaks into smaller pieces, and each piece grows into a new filament. This is distinct from binary fission (single-celled division) or budding (outgrowth formation).
