Question

The gymnospermic endosperm differs from an angiospermic endosperm, because in gymnosperms it is

• A. Haploid and developed from female gametophyte
• B. Diploid and developed from female gametophyte
• C. Triploid and developed after fertilization
• D. Triploid and developed before fertilization

Answer 1

The correct option is A Haploid and developed from female gametophyte

In angiosperms, endosperm is triploid (3n) and is formed after the fertilisation. The diploid secondary nucleus fuses with the male gamete to form a triploid primary endosperm nucleus which then forms the endosperm.

In gymnosperms, endosperm is formed before fertilisation, from the female gametophyte and thus, it is haploid (because female gametophyte is haploid).

So, the correct answer is 'Haploid and developed from female gametophyte'.
