Question

In angiosperms, the endosperm is

• A. Persistent female gametophyte
• B. Formed after fertilization
• C. Formed before fertilization
• D. Short lived

Answer 1

Answer: (B)

Formed after fertilization

Double fertilization process is observed in angiosperms in which syngamy takes place in the beginning. After syngamy the pollen tubes releases two male gametes, one fuses with the nucleus of the egg cell and the other with the central cell and forms the primary endosperm nucleus (PEN). The process is called as triple fusion as endosperm is triploid in nature.

So the correct option is 'Formed after fertilization'.
