Q.

A multicelluar, filamentous alga exhibits a type of a sexual life cycle in which the meiotic division occurs after the formation of zygote. The ad adult filament of this alga has
(a) Haploid vegetative cells and diploid gametangia
(b) Haploid vegetative cells and diploid gametangia
(c) Diploid vegetative cells and haploid gametangia
(d) Haploid vegetative cells and haploid gametangia

Q. Zygotic meiosis is associated with which of the following life cycle pattern?

Q. Zygote of an organism developed after syngamy undergoes meiosis to form haploid spores, which divide mitotically and form the gametophyte. The organism must have ________ life cycle.

Q. Zygotic meiosis is shown by
I. Algae II. Fungi III.Bryophytes IV.Pteridophytes

Q. Which of the following statements is/are correct?
(A) Meiosis involves two sequential cycles of each event, i.e., DNA replication and nuclear division.
(B) Meiosis involves pairing of homologous chromosomes and recombination between them.
(C) Four haploid cells are formed at the end of meiosis-I.
(D) Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms.
