Question

Which of the following is haploid in gymnosperm?

• A. Pollen grain, megaspore, root
• B. Pollen grain, megaspore, nuclues
• C. Megaspore mother cell, root, leaf
• D. Endosperm, Pollen grain, Megaspore

Answer 1

The correct option is D Endosperm, Pollen grain, Megaspore

Gymnosperms are having a haploid endosperm. But, angiosperms have a triploid endosperm due to the double fertilization. The pollen grain is the haploid in nature. Therefore, in gymnosperms, the pollen grains and the megaspores are the haploids. The functional megaspores from the embryo sac. The endosperm is formed prior to the fertilization and hence it is haploid.
