Question

..........

Answer 1

Answer:

During Vegetative Production meiosis occur in Spirogyra

Answer 2

Explanation:

• During the development of the zygospore, the meiosis occurs in the Spirogyra. The breakdown of the female gametangia causes the creation of the zygospore in the spirogyra.
• This zygospore remains stable at the bottom of the pond until it gets a favorable condition.  When it gets the proper condition then the diploid nucleus of the Zygospore enters in the meiosis cell division to form four haploid nuclei.
• Three of the haploid nuclei gets degenerate and the zygospore became enlarged.
