a. Fucus

b. Funaria

c. Marchantia

d. Chlamydomonas

Answer:- (d) Chlamydomonas

Explanation: Zygotic Meiosis is one of the main characteristics of Chlamydomonas and Zygotic meiosis occurs in Chlamydomonas only out of all the options mentioned above.

• Meiosis is a type of cell division that reduces the number of chromosomes by half. Zygotic meiosis is that type of meiosis that occurs in a zygote (it is a fertilised egg cell)

• A zygote is a diploid cell that is created as a result of the combination of two opposite-sex cells. In some living organisms (For instance, cellular slime molds), the zygote undergoes meiosis to generate haploid individuals. Therefore, Zygotic meiosis can be explained as the division of zygote through meiosis to generate haploid cells which ultimately create haploid individuals

• In other words, Zygotic meiosis can be defined as the type of cell division which constructs haploid cells from a zygote. In these organisms (For instance in fungi and green algae), the multicellular stage is characterised by haploid. Therefore, once the diploid zygote has been built, it needs to undergo meiosis to generate haploid spores. Then, those haploid spores divide by mitosis to produce multicellular haploid individuals

• Chlamydomonas (a genus of single-celled green algae and family of chlamydomonadaceae) reproduces by the both asexual and sexual methods. At the time of sexual reproduction, the cells function as gametes. 2 gametes of the opposite sex combines and produce a quadriflagellate (or biflagellatye) zygote (or zygospore). The flagellated zygote loses flagella and becomes non-motile and then goes under the resting phase. A thick wall is generated surrounding this cell. The zygote undergoes meiosis division. As a result, four zoospores are formed which develop into a Chlamydomonas plant
