are the antipodals hapliod or diploid?
antipodal cells r haploid
To determine whether antipodals are haploid or diploid, we can refer to plant reproductive biology.
Antipodals are one of the three types of cells found in the female gametophyte (embryo sac) of flowering plants. The other two types are the egg cell and the two synergids. The antipodal cells are located at the opposite pole (antipodal position) of the embryo sac from the egg cell.
The female gametophyte or embryo sac is formed through a process called megasporogenesis, which involves the formation of haploid cells. Therefore, all the cells within the embryo sac, including the antipodals, are initially haploid.
However, after fertilization occurs, the antipodals (along with the synergids) generally degenerate and eventually disappear. This means that they do not contribute to the formation of the embryo or endosperm, which develop from the fusion of haploid egg cell and sperm cell, and fusion of two polar nuclei with one sperm cell, respectively. As a result, the antipodal cells do not undergo further cell division or become involved in the development of the plant.
In summary, antipodal cells are initially haploid but do not give rise to any structures in the plant embryo. Therefore, they remain haploid throughout their existence within the female gametophyte.
