In a microsporangia of an pollen sac, there are numerous diploid microsporocytes. These microsporocytes undergo meiosis to produce 4 haploid microspores each.. Each microspore than undergoes mitosis to produce two nuclei which are generative and tube nucleus. Male gametophytes are now formed and they go on to mature during pollen germination. In this process, the tube nucleus makes the pollen tube while the generative nucleus mitotically divides to form two male nuclei.

A diploid megasporocyte in the nucellus of an ovule undergoes meiosis to produce 4 haploid megaspores. 3 of the 4 megaspores degenerate and is absorbed by the nucellus while the 1 remaining megaspore 'mitotically' divides 3 times to form 8 nuclei. 3 of the nuclei move to one end(top) of the ovule to form antipodal cells, while 3 more nuclei move to the micropyle to form one egg cell with 3 synergid cells. The remaining two nuclei migrate to the centre to remain as polar nuclei.

Double fertilization begins with pollen germination where a pollen tube emerges from a pollen which pierces the style. The pollen tube grows till it reaches the micropyle. The two generative nucleus mitotically divides to form two nuclei. The tube nucleus degenerates and none male nuclei fuses with an egg cell forming a diploid zygote. The other nucleus fuses with two polar nuclei forming a triploid endosperm which will go on to develop as food storage.
