Which one of the following is opposite part of micropylar end of ovule?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Chalaza
An ovule has two ends. The micropylar end carries the small opening, the micropyle, through which the pollen tube usually enters. The end opposite to it is the chalaza, the basal part of the ovule.
Option (1) Hilum — Incorrect. The hilum is the point where the body of the ovule joins the funicle. It is a junction, not the end facing the micropyle.
Option (2) Chalaza — Correct. The micropyle is the small opening at the tip of the ovule. Opposite the micropylar end is the chalaza, the basal part of the ovule.
Option (3) Funicle — Incorrect. The funicle is the stalk that attaches the ovule to the placenta.
Option (4) Nucellus — Incorrect. The nucellus is the mass of cells inside the integuments that holds the embryo sac. It fills the ovule; it is not one of its ends.
