... The plant body is the diploid sporophyte. Meiosis occurs in separate organs to produce male and female gametophytes. The male gametophyte, the pollen, lands on the stigma of the flower. The pollen grain then grows a tube down to the ovule, the female gametophyte. The 2 sperm nuclei migrate down the ...
