Explanation:
Detailed explanation-1: -Microspores are haploid, and are produced from diploid microsporocytes by meiosis.
Detailed explanation-2: -After the formation of the four haploid microspores occurs it fuses to form pollen grain and the development of the pollen grain walls starts. Hence pollen grain is a haploid structure.
Detailed explanation-3: -The end result of meiosis is ALWAYS haploid cells. In plants, the pollen grain and ovules have the male and female gametes respectively, which have been produced as a result of meiosis.
