The correct development sequence is as follows: Sporogenous tissue – pollen mother cell – microspore tetrad – Pollen grain – male gamete During the development of microsporangium, each cell of the sporogenous tissue acts as a pollen mother cell and gives rise to a microspore tetrad, containing fourRead more
The correct development sequence is as follows:
Sporogenous tissue – pollen mother cell – microspore tetrad – Pollen grain – male gamete
During the development of microsporangium, each cell of the sporogenous tissue acts as a pollen mother cell and gives rise to a microspore tetrad, containing four haploid microspores by the process of meiosis (microsporogenesis). As the anther matures, these microspores dissociate and develop into pollen grains. The pollen grains mature and give rise to male gametes.
Both events (microsporogenesis and megasporogenesis) involve the process of meiosis or reduction division which results in the formation of haploid gametes from the microspore and megaspore mother cells. Microsporogenesis results in the formation of haploid microspores from a diploid microspore mothRead more
Both events (microsporogenesis and megasporogenesis) involve the process of meiosis or reduction division which results in the formation of haploid gametes from the microspore and megaspore mother cells.
Microsporogenesis results in the formation of haploid microspores from a diploid microspore mother cell. On the other hand, megasporogenesis results in the formation of haploid megaspores from a diploid megaspore mother cell.
Microsporogenesis:- 1. It is the process of the formation of microspore tetrads from a microspore mother cell through meiosis. 2. It occurs inside the pollen sac of the anther. Megasporogenesis:- 1. It is the process of the formation of the four megaspores from a megaspore mother cell in the regionRead more

2. It occurs inside the pollen sac of the anther.
Megasporogenesis:- 1. It is the process of the formation of the four megaspores from a megaspore mother cell in the region of the nucellus through meiosis
The male gametophyte or the pollen grain develops inside the pollen chamber of the anther, whereas the female gametophyte (also known as the embryo sac) develops inside the nucellus of the ovule from the functional megaspore.
