Read the following statements regarding the development and structure of a typical angiosperm embryo sac: A. The egg apparatus consists of two egg cells and one synergid. B. The large central cell is situated below the egg apparatus and contains two polar nuclei. C. Three cells are grouped together at the micropylar end to constitute the antipodals. D. The synergids have special cellular thickenings at the micropylar

Step-by-step solution

Statement A is incorrect because the egg apparatus consists of two synergids and one egg cell, not two egg cells and one synergid. Statement B is correct as the large central cell contains two polar nuclei and is located below the egg apparatus. Statement C is incorrect because the antipodals are a group of three cells located at the chalazal end, whereas the egg apparatus is at the micropylar end. Statement D is correct as synergids possess the filiform apparatus at their micropylar tip, which guides the pollen tu
