Answer 1

Answer:

d) fusion of two polar nuclei of an embryo sac

Answer 2

Dear Student,

◆ Answer - (a)

The main embryo developed from the structure formed as a result of *double fertilization*.

◆ Double fertilization -

- In angiosperms, one sperm cell fertilizes egg cell to form a zygote and one sperm cell combines with polar nuclei to form endosperm. This is called double fertilization.

# Significance of double fertilization -

- Endosperm develops only if ovum is fertilized.

- Endosperm gives nourishment to the developing embryo.

- It results in rapid multiplication of plants.

Thanks dear. Hope this helps..
