Answer #1

In Spirogyra,conjugation is mainly of two types.

1.Scalariform conjugation

2.Lateral conjugation

In both types of conjugation,male gamete passes through an aperture and enters in the female gametangium,where it fuses with female gamete to form zygospore.

The two gametes are morphologically alike but differ in their behavior.

In case of Chlamydomonas,sexual reproduction of anisogamous type takes place,where two haploid gametes fuse together to form diploid zygote.This zygote secretes a thick wall and becomes oospore or zygospore for the purpose of perennation.

The correct answer is zygospore
