Question

Select the wrong statement among the following.

• A. Life cycle in Chlamydomonas is haplontic
• B. Life cycle in Marchantia in haplo-diplontic
• C. In plants both haploid and diploid cells can divide by mitosis
• D. In diplontic life cycle, meiosis occurs in zygote.

Answer 1

The correct option is D

In diplontic life cycle, meiosis occurs in zygote.

In diplontic life cycle, the sporophyte is dominant and originates from the zygote by mitosis. Meiosis occurs before fertilisation i.e. during the formation of gametes in the gametophytic stage.
