As we know the embyosac is the female gametophyte that is 8nucleated and 7celled
the embryosac contains three cells on the mycropylar side named two synergids and one egg cell each synergid contains filiform apparatus that guids the entry of the pollen tube
and middle central contains two polar nuclei
and embryo sac contains antipodals on the chalazal end these antipodals are considered as the vegetative cells of the embryosac and these degenerate after fertilization the polar nuclei present in the central cell fused to form diplod secondary nucleus and this diploid secondary nucleus fuse with male gamete to form triploid endosperm

In the following question, a Statement of Assertion (A) is given follo...
Assertion: The chalazal cells of the embryo sac are called antipodal cells.
Reason: They play a nutritive role for the embryo sac.
Explanation:
- The chalazal cells are located at the chalazal end of the embryo sac, which is the opposite end to the micropyle.
- The antipodal cells are also located at the chalazal end of the embryo sac.
- Both the assertion and the reason are true in this case. The chalazal cells of the embryo sac are indeed called antipodal cells.
- However, the reason given in the statement is not the correct explanation for the assertion.
- The antipodal cells do not play a nutritive role for the embryo sac. Instead, they have other functions.
- The antipodal cells are believed to have a role in embryogenesis, but their exact function is not yet fully understood.
- Some of the proposed functions of the antipodal cells include providing structural support to the embryo sac, regulating the growth of the embryo sac, and possibly playing a role in nutrient uptake or secretion.
- The primary role of the antipodal cells is still a subject of research and debate among scientists.
- Therefore, the correct answer is option B: Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
- It is important to analyze both the assertion and the reason separately and evaluate their individual accuracy and relationship to each other before arriving at the correct answer.
