Important Question of Sexual Reproduction in Flowering Plants

Differentiate between microsporogenesis and megasporogenesis.  Microsporogenesis vs Megasporogenesis Comparison of Microsporogenesis and Megasporogenesis S.No Microsporogenesis Megasporogenesis 1 In this process, haploid microspores are formed from diploid mother cells or pollen mother cells (MMC or PMC). In this process, haploid megaspores are formed from diploid mother cells (MMC). 2 It occurs inside the microsporangium or pollen sac of an anther. It occurs inside the nucellus of ovule or megasporangium. 3 There are many microspore mother cells in a microsporangium. There is generally a single megaspore mother cell in a megasporangium. 4 The four microspores formed from a single microspore mother cell are generally arranged in a tetrahedral structure. The four megaspores formed from a megaspore mother cell are arranged in the form of a linear tetrad. 5 All the four microspores arranged in a tetrahedral tetrad are functional. Only one megaspore remains functional while the other three degenerate. 6 The mi…
