Flowering structure in which haploid make gametophytes are produced

• A. Anther
• B. Ovary
• C. Stamen
• D. Petal

Answer: (A)

In flowering plants, the haploid male gametophyte is the pollen grain, and it is produced inside the anther. The anther contains pollen sacs where diploid pollen mother cells undergo meiosis to make haploid microspores, which then develop into pollen grains—the male gametophytes. The ovary, by contrast, is where female gametophytes (embryo sacs) form within ovules, so it’s not the site of pollen production. The stamen is the overall male reproductive structure, but the specific place that makes the pollen is the anther, and petals aren’t involved in gametophyte production. Thus, the anther is where haploid male gametophytes are produced.
