Raghav is trying to understand when plant cells are haploid (N) or diploid (2N) during sexual reproduction. Which of the following statements is correct?
The microspore and megaspore are diploid (2N) cells that undergo meiosis, and the fertilized zygote remains haploid (N).
The microspore and megaspore are haploid (N) cells formed after meiosis, and fertilization restores the diploid (2N) number in the zygote.
The pollen and ovule mother cells are haploid (N) before meiosis and form diploid gametes after meiosis.
The pollen and ovule mother cells are diploid (2N), and meiosis produces haploid gametes, but fertilization does not restore the diploid number.
