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)


HOPE HELP U

The central cell is a highly active cell that performs several important functions in the embryo sac. The fusion of the secondary nucleus or the polar nuclei with the sperm nucleus gives rise to the primary endosperm nucleus, which is generally triploid.
