Conjugation in Spirogyra is a form of sexual reproduction where two filaments align, and a conjugation tube forms between cells. The protoplast of one cell transfers through this tube to fuse with t

The significance of conjugation in Spirogyra is:

• It introduces genetic variation into the population, as genetic material from two different parent cells combines.
• This genetic diversity enhances the species' ability to adapt to changing environmental conditions.
• The resulting zygospore is a thick-walled, dormant structure that can survive harsh conditions like drought or extreme temperatures, ensuring the species' survival until favorable conditions return.
