Options
- AA-III, B-IV, C-I, D-II
- BA-II, B-IV, C-I, D-III
- CA-III, B-I, C-IV, D-II
- DA-IV, B-III, C-II, D-I
Correct answer
A. A-III, B-IV, C-I, D-II
Step-by-step solution
A typical angiosperm embryo sac consists of an egg apparatus at the micropylar end, three antipodal cells at the chalazal end, and a large central cell. The egg apparatus comprises two synergids and one egg cell (the female gamete). The synergids possess special cellular thickenings at the micropylar tip called the filiform apparatus. The central cell is the largest cell of the embryo sac and contains two polar nuclei. The antipodals are three cells located at the chalazal end. Therefore, the correct matching is A-
