Question

Select the correct statement(s) regarding the structure of a mature embryo sac.
(i) Egg apparatus is situated towards chalazal end.
(ii) Antipodal cells are situated towards micropylar end.
(iii) A typical angiospermic embryo sac is $7$-celled, $8$-nudeate at maturity.

• A. (i) only
• B. (ii) only
• C. (iii) only
• D. (i), (ii) and (iii)

Answer 1

Answer: (C)

Three cells which are grouped together at the micropylar end make the egg apparatus. Three cells at the chalazal end are called antipodals. A typical angiosperm embryo sac, at maturity, though 8-nucleate is 7-celled. So, the correct option is '(iii) only'.
