Antipodal cells are present at -
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Chalazal end of embryo sac
A mature embryo sac is 7-celled and 8-nucleate. Its cells are arranged in a fixed way. At the micropylar end is the egg apparatus (two synergids and one egg cell). At the chalazal end are the three antipodal cells. In the centre is a large central cell with two polar nuclei.
(1) Micropolar end of embryo sac — Incorrect. The micropylar end holds the egg apparatus, not the antipodals.
(2) Chalazal end of embryo sac — Correct. The three antipodals are grouped at the chalazal end, opposite the egg apparatus.
(3) Center of embryo sac — Incorrect. The centre is taken up by the large central cell with its two polar nuclei.
(4) Outside the embryo sac — Incorrect. The antipodals are cells of the embryo sac itself, so they lie inside it.
