Question

meiosis in a plant occurs when there is change
a.From gametophyte to sporophyte
b.From sporophyte to gametophyte
c.From gametophyte to gametophyte
d.Sporophyte to sporophyte​

Answer 1

Answer:

b.From sporophyte to gametophyte.

Explanation:

Sporophyte is a diploid condition while gametophyte is a haploid condition and meiosis is a reductional division(from diploid to haploid). So,meiosis in plants occurs when there is change from sporophyte to gametophyte.

Answer 2

Answer:

Meiosis in a plant occurs when there is a change from sporophyte to gametophyte.

Explanation:

The sporophyte is the diploid multicellular phase in the life cycle of a plant. In plants when a sporophyte undergoes meiosis or reduction division it leads to the formation of haploid spores, which after undergoing mitosis grows into an entirely new haploid called gametophyte.

• We can deduce gametophyte as the plant or phyte that produces gametes (gameto‑).
• In angiosperms, diploid sporophyte undergoes meiosis in stamens and carpels leading to the formation of haploid megaspore, which after the growth by mitosis forms haploid microgametophyte or pollen in stamen and megagametophyte containing megagametes or eggs in the ovary of the carpel.
• After the pollination both the male and female gamete fuse together by a process called syngamy and form a diploid zygote. A zygote or fertilized ovule undergoes mitosis and develops into a seed.
