please explain whether the Pollen Grain is haploid or diploid also
provide reason for your answer
We considered the pollen grain to be diploid in some cases that is
to 2n, it is the male gametophyte
When it comes to the female part of a flower, then the embryo sac
for even considering the functional megaspore, then it is
considered to be haploid, that is n, why is it so?

Dear Student, Pollen grain is the male gametophyte and haploid in
structure The central Nucleus of pollen grain undergoes mitosis to
form a generative cell and tube cell This generative cell again
undergo mitosis to form 2 haploid male gametes that fuse with egg
and polar nuclei of female to form a diploid zygote and triploid
endosperm respectively Regards
