Why the primary endosperm nucleus is triploid?

HEY MATE

DURING DOUBLE FERTILIZATION

WEEKEND MALE GAMETE OF POLLAN GRAIN REACHES TO EMBRYO THROUGH MICROPYLAR END

AND ENTERS .....

OTHER MALE GAMETE (N) FUSE WITH POLAR NUCLIE (2N)

TO FORM PRIMARY ENDOSPERM NUCELUS (PEN)(3N)
AND THE PROCESS IS KNOWN AS TRIPLE FUSION

AS 2N+N=3N
HENCE IT IT'S TRIPLOID

THE CENTRAL CELL IN WHICH PEN IS PRESENT IT'S KNOWN AS PRIMARY ENDOSPERMIC CELL(PEC)
