Meiosis occurs in the anthers and ovary of the angiosperms. Meiosis helps in the formation of spores in plants. The pollen mother cell in the anthers undergoes meiosis to haploid microspores. The megasporocyte in the ovule divides by meiosis to form mega spores.
The anthers produce pollen grains, the male gametes by both mitosis and meiosis. The cells of the anthers divide by mitosis to form the pollen mother cells. Microspores are formed in groups of four and they develop into pollen grains. The megasporocye divides by meiosis to form four haploid megaspores, one of which continues to develop as the other megaspores dissolve.
