Hola, colegas.
Estoy traduciendo palabras sueltas de un glosario de biología.
Encontré "polar nudei" pero la verdad es que no tengo idea de qué se trata.
Gracias de antemano.

Explanation:
http://en.mimi.hu/biology/polar_nuclei.html

polar nuclei
The two nuclei that are formed at each pole of the angiosperm embryo sac. They will fuse with a male nucleus to form a primary endosperm nucleus.
Full article >>>

polar nuclei Two of the eight haploid nuclei of a megagametophyte that migrate, one from each end, to the middle of the embryo sac. These two nuclei fuse with a sperm nucleus during double fertilization.
Full article >>>

The two central cell maternal nuclei (polar nuclei) that contribute to the endosperm arise by mitosis from a single meiotic product.
Full article >>>

One sperm cell fuses with the egg forming the diploid zygote.
The other sperm cell fuses with the polar nuclei forming the endosperm nucleus. Most angiosperms have two polar nuclei so the endosperm is triploid (3n).
Full article >>>

The events of "double fertilization" of the egg and polar nuclei by the two sperm cells. Image from Purves et al.
Full article >>>

Double fertilization: The union of one male gametophyte nucleus with the ovum nucleus and another male gametophyte nucleus with the polar nuclei to form the endosperm in seed plants. See also pollen grain.
