Glossary of "Plant Biology (1st ed.)" by Graham et al. (2003)

  • A unique characteristic of flowering plants in which two sperm nuclei fuse with separate nuclei to produce a diploid zygote and a triploid endosperm.

Glossary of "Life (9th ed.)" by Sadava et al. (2011)

  • In angiosperms, a process in which the nuclei of two sperm fertilize one egg. One sperm’s nucleus combines with the egg nucleus to produce a zygote, while the other combines with the same egg’s two polar nuclei to produce the first cell of the triploid endosperm (the tissue that will nourish the growing plant embryo).
