Endosperm is a triploid tissue in angiosperms because of
Fusion of second male gamete with secondary nucleus
Both of the above
Formation of endosperm before fertilization
Correct answer: (c)
Solution: Endosperm is a triploid tissue in angiosperms, because double fertilization results in the formation of a diploid zygote and a triploid endosperm. The female gametophyte or embryo sac has an egg nucleus and two polar nuclei. One sperm fertilizes the egg nucleus and forms the zygote, 2n. Another sperm joins the two polar nuclei forming the triploid (3n) nutritive tissue, called as the endosperm.
