Vedclass · Answer

(D) In plants,both haploid and diploid cells can divide by mitosis. This ability leads to the formation of different plant bodies—haploid and diploid. The haploid plant body produces gametes by mitosis. This plant body represents a gametophyte. Following fertilization,the zygote also divides by mitosis to produce a diploid sporophytic plant body. Haploid spores are produced by this plant body by meiosis. Thus,during the life cycle of any sexually reproducing plant,there is an alternation of generations between gamete-producing haploid gametophyte and spore-producing diploid sporophyte. Depending on whether the haploid or diploid phases are dominant,plants exhibit different patterns: $1$. Haplontic life cycle,$2$. Diplontic life cycle,and $3$. Haplo-diplontic life cycle. Therefore,all these types are observed in plants.

Which of the following types of alternation of generations is observed in plants?
