Question

Which is haploid in Gymnosperm?

• A. Root, shoot, endosperm
• B. Endosperm, pollen grain, megaspore
• C. Root, leaf, bud
• D. Bulbil, buds, microspore

Answer 1

The correct option is B Endosperm, pollen grain, megaspore

Gymnosperms have a haploid endosperm. Whereas angiosperms have a triploid endosperm as a result of double fertilization.

Pollen grain is haploid in nature as it is the male gamete which fuses with female gamete to form the zygote.

Megaspore is haploid in nature in gymnosperms, whereas the megaspore mother cell is diploid in nature and it undergoes meiosis resulting in the formaiton of four megaspores.
