Question
Pollen grains are formed in the anther of the flower by which sequence of events? Haploid microspore mother cells divide by mitosis to form four diploid microspores. Each microspore develops into a pollen grain by meiosis. Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis. Diploid megaspore mother cells divide by mitosis to form four diploid megaspores. Each megaspore develops into a pollen gram by meiosis. Diploid microspore mother cells divide by mitosis to form four haploid microspores. Each microspore develops into a pollen grain by meiosis. Haploid microspore mother cells divide by meiosis to form four diploid microspores. Each microspore develops into a pollen grain by mitosis.Explanation / Answer
Ques: Pollen grains are formed in the anther of the flower by which sequence of events?
Answer:
b) Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis.
Explanation: Each pollen sac in the anther of the flower contains microsphere mother cells which are diploid (2n). These mother cells divide by meiosis and results into the formation of four haploid (n) microphores. Subsequently each microspheres then develops into a pollen grain by mitosis.
