Vedclass · Answer

(A) In angiosperms,the development of the male gametophyte from a pollen mother cell $(PMC)$ occurs as follows:$1$. The $PMC$ undergoes meiosis to produce a microspore tetrad (four haploid microspores).$2$. Each microspore then undergoes two mitotic divisions to form the mature male gametophyte (pollen grain).$3$. The first mitotic division produces a vegetative cell and a generative cell.$4$. The second mitotic division occurs in the generative cell to produce two male gametes.Therefore,the process involves one meiotic division followed by two mitotic divisions.
