Ploidy of Microspore Tetrads — NEET Biology
✅ Asked in NEET 2026Microsporogenesis: As the anther develops, the cells of the sporogenous tissue undergo meiotic divisions to form microspore tetrads. What would be the ploidy of the cells of the tetrad?
During microsporogenesis, sporogenous tissue cells undergo meiosis I and II to produce microspore tetrads. Each cell in a tetrad is haploid (n), having half the chromosome number of the diploid (2n) parent cell. Students often confuse the ploidy by thinking tetrads remain diploid or fail to account for both meiotic divisions. Remember: meiosis reduces ploidy by half, so if the anther is diploid (2n), microspore tetrads are haploid (n). This concept directly tests understanding of meiosis and gametogenesis, core NEET topics.
Arrange the following in correct developmental sequence related to microsporogenesis: A. Microspore tetrads, B. Sporogenous tissue, C. Pollen grains, D. Pollen mother cells.
