During sexual reproduction, the life cycle includes the change of ploidy; the alternation of haploid (n) and diploid (2n) stages. They are, haplontic, diplontic and haplodiplontic. In a haplontic life cycle, the haploid stage is typically multicellular and results in the formation of a diploid (2n) cell, which is a zygote. 11.

NCERT NCERT Exemplar NCERT Fingertips Errorless Vol-1 Errorless Vol-2. Does the potential difference between two points depend on the choice of zero potential or zero potential energy? Correct Answer: Ustilago. During sexual reproduction, the life cycle includes the change of ploidy; the alternation of haploid (n) and diploid (2n) stages. As C=(1/ V)Q, can you say that the capacitor C is proportional to the charge Q? A life cycle in which meiosis occurs shortly after fertilization, and most of the life cycle is passed as a haploid. Instead, they fuse with gametes of the opposite sex and produce a diploid cell which is known as a zygote. Improve concepts using videos, connect with students and teachers globally. This phenomenon could be explained with sporic meiosis – the process of formation of spores. Life cycle of seed plants is (1) haplontic (2) haplo-diplontic (3) diplontic (4) diplo-haplontic . The zygote undergoes meiosis, which results in the formation of haploid (n) cells. Available here. Within the sporophyte, meiotic cell division occurs and results in haploid (n) spores.
