Vedclass · Answer

(B) $1$. The microspore mother cell $(MMC)$ is diploid $(2n)$. It undergoes one meiotic division (meiosis) to produce four haploid $(n)$ microspores,which are arranged in a microspore tetrad.$2$. Each microspore then develops into a pollen grain. During this development,the nucleus of the microspore undergoes one mitotic division to form a vegetative cell and a generative cell.$3$. Therefore,the formation of a mature pollen grain from a microspore mother cell involves one meiosis followed by one mitosis.
