Look fella..


¶¶ OVARY : site of fertilization.
¶¶ STAMEN : male reproductive part.
¶¶ PISTIL : female reproductive part.


• MALE GAMETES enters through MICROPHYLE.
• POLLEN TUBE contain male gametes.
• MALE GAMETES is 2 in number and FEMALE GAMETES is 8 in number.


Now coming on female gametes which are 8 in number...

√ 3 cell doesn't produce present at the end of CHALAZA.. known as { ANTIPODEL CELLS } it doesn't participate in fertilization.

√ SYNEGID are present in the side of egg . it also not participate in fertilization


Now.. after subtracting [ 3 antipodel cells and 2 synergeid ]

∆∆ we have now 3 cells in female gametes...

in this 3

> 2 is POLAR NUCLEI
> 1 is EGG


||| EGG ( active) + synagied ( inactive) = APPARATUS



< first="" fertilization="" is="" called="" syngamy="" />
n ( male ) + n ( female ) = 2 n ( zygote)


developed in SEED.


>> triple fusion

Polar nuclei + egg

2n + n = 3n ( endosperm )

developed in FRUIT.




now...


¶¶ SYNGAMY and TRIPLE FUSION = DOUBLE FERTILIZATION.


hope gonna be helpful..!
