What happens to the polar nuclei during the process of triple fusion in Angiosperms?

  1. They degenerate
  2. They form the primary endosperm nucleus
  3. They develop into the seed coat
  4. They fuse with the egg to form twin embryos
Show answer and explanation

Correct answer: They form the primary endosperm nucleus

Triple fusion involves the fusion of one male gamete with the two polar nuclei (or a secondary nucleus) in the central cell of the embryo sac. This results in the formation of the Primary Endosperm Nucleus (PEN).
