AGO9 protein and gene silencing in plant gametes Female gametes in flowering plants develop from a meiotic division of a precursor cell followed by mitotic divisions of one of the haploid cells to yield the gametophyte. This study identifies AGO9, a protein involved in RNA interference, as a ...

In flowering plants, the formation of gametes depends on the differentiation of cellular precursors that divide meiotically before giving rise to a multicellular gametophyte. The establishment of this gametophytic phase presents an opportunity for natural selection to act on the haploid plant genome by ...
- Dioecious Plants: These are plants that have male and female reproductive organs on separate individuals. This means that one plant will produce only male gametes and another will produce only female gametes. 2. Analyze the Options: - Option 1: Papaya: Papaya is known to be a monoecious ...
What do we call the diploid cell resulting from the fusion of two haploid gametes? Fill in the blank. The transfer of the male gametes to the female gametes in plants is called ___. What is the name given to the division of the cytoplasm to form two separate daughter cells? There ...
