Read the following statements :

A. Out of the four megaspores produced during meiosis, all four megaspores develop into the embryo sac.

B. The surviving megaspore undergoes three rounds of mitotic division without cytokinesis to form eight haploid nuclei.

C. Three antipodal cells are located at the micropyle end of the embryo sac.

D. The central cell of the embryo sac contains two polar nuclei.

E. The egg cell and synergids are located near the chalazal end of the embryo sac.

Choose the Correct statements.

B and D

The correct answer is Option (2) – B and D

The embryo sac, also known as the female gametophyte, is a crucial structure within the ovule of a flowering plant. It is formed through the process of megasporogenesis, which involves the differentiation and development of a single megaspore mother cell within the ovule. The megaspore mother cell undergoes meiosis to produce four haploid megaspores. Out of these four megaspores, three degenerate and only one megaspore survives and develops into the embryo sac.

The surviving megaspore undergoes three rounds of mitotic divisions without cytokinesis, resulting in the formation of eight haploid nuclei. These nuclei become organized into different cells within the embryo sac through the formation of cell walls. The organization of the nuclei and cells within the embryo sac varies among different species, but a common pattern consists of three antipodal cells at the chalazal end, two synergid cells and egg cell near the micropyle, a centrally located large central cell containing two polar nuclei.
