A

Megaspore mother cell, root, leaf
B

Pollen grain, megaspore, nucellus
C

Pollen grain, megaspore, root
D

Endosperm, pollen grain, megaspore

In gymnosperms, the pollen grains and the megaspores are haploid and develop as a result of meiosis in the respective mother cells. The functional megaspore forms the female gametophyte which acts as endosperm and hence is haploid.
