Pollination is the placement of the pollen on the stigma of the carpal. Once the pollen lands on the stigma, a series of chemical reactions takes place allowing the pollen grain to begin producing a structure called the pollen tube. As this is happening, the generative nucleus will divide and produce 2 sperm nuclei. This pollen grain with the pollen tube and 3 nuclei is considered the mature gametophyte. The pollen tube will work its way through the style of the carpal and touch the micropyle of the ovule. Here the sperm nuclei will enter the embryo sac and fertilize the egg and the two polar nuclei; hence the term double fertilization. The fertilized egg (2N) (zygote) will develop into the immature seed plant, while the (3N) central cell will develop into the endosperm or food storage area of the seed.

The zygote is formed inside the ovule when a sperm nucleus from the pollen joins with an egg nucleus inside the ovule.

B) a primary endosperm cell to produce one cell with one triploid nucleus the triploid body develops in to the endosperm which is the seeds food storage and develops in to testa which is the seed coat.
