Fertilisation in plants occur in the:

• A. Embryo sac
• B. Style
• C. Pollen tube
• D. Stigma

Answer 1

The correct option is A

Embryo sac

Fertilisation in plants occurs in the embryo sac. The pollen tube enters into the embryo sac through micropyle. At this time, the pollen tube bursts open, gametes are released from the pollen tube and enter into the embryo sac. One of the gametes fuses with the egg and the other fuses with the secondary nucleus.
