Pollen Development:
A pollen grain is an immature male gametophyte.
It is produced within the sporangium of the anthers.
The diploid microspore mother cell will undergo meiosis and form 4 haploid microspores.
The microspores nuclei will undergo mitosis and produce a tube nucleus and a generative nucleus.
A thick wall forms around the spore in a specific pattern, producing the pollen grain or immature male gametophyte.
Are the nuclei inside the pollen grain monoploid or diploid?
monoploid (haploid)
Reply:The pollen grain being the male part of the new plant is haploid(monoploid)
