Answer:

Angiosperms have seeds with an 3n endosperm due to double fertilization.

Explanation:

  • Double fertilization is found only in flowering plants.
  • In angiosperms, the female gametophyte does not grow after reaching eight nucleate stage.
  • After fertilization and triple fusion, the zygote and primary endosperm are created and further growth of embryo sac continues.
  • Triple fusion is the fusion of two haploid polar nuclei of female gametophyte and one male nuclei. This results in a  3n nucleus.
  • The developing embryo obtains nutrition from the endosperm.
  • If fertilization fails no endosperm is formed.
