In haploid organisms that undergo sexual reproduction, name the stage in the life cycle when meiosis occurs. Give reasons for your answer.
Answers (1)
In haploid organisms which reproduce by sexual reproduction, gametes are formed by meiotic division and the number of chromosomes is half of the total. The life cycle stage where meiosis occurs is known as the sporophytic generation and is represented by a single-celled zygote. In such plants, the gametophytic phase (haploid) is the dominant phase. Such a life cycle is called haplontic.
