Question

Polar nuclei become a part of __________ after fertilisation in angiosperms.

• A. zygote
• B. primary endosperm nucleus
• C. Both a and b
• D. None of the above

Answer 1

The correct option is B primary endosperm nucleus

The two polar nuclei present in the central cell of embryo sac fuse with the male gamete to form a primary endosperm nucleus (PEN).

Zygote is formed by the fusion of the egg cell and another male gamete.
Polar nuclei are not involved in the formation of the zygote.
