Question

Select the haploid structures of gymnosperms :

• A. Leaf, embryo, endosperm
• B. Embryo, endosperm, megaspore
• C. Pollen, embryo, endosperm
• D. Endosperm, pollen, megaspore

Answer 1

The correct option is D Endosperm, pollen, megaspore

Gymnosperms do not undergo double fertilization, therefore in haploid stage of the gymnosperm life cycle, the plants have only one set of chromosome, Thus haploid microspores are released into air as pollen and in gymnosperm endosperm is formed before fertilization from the female gametophyte(n). Hence it is haploid.

So, the correct option is 'Endosperm, pollen, megaspore'.
