Match List I with List II
| LIST I | LIST II |
|---|---|
| A. Attaches ovule to the placenta | I. Hilum |
| B. Regions where ovule fuses with the stalk | II. Chalaza |
| C. Place where integuments are not present | III. Funicle |
| D. Basal part of ovule | IV. Micropyle |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-III, B-I, C-IV, D-II
(A) Attaches ovule to the placenta — this matches (III) Funicle. The funicle is the stalk by which the ovule hangs from the placenta.
(B) Regions where ovule fuses with the stalk — this matches (I) Hilum. The hilum is the junction between the body of the ovule and the funicle.
(C) Place where integuments are not present — this matches (IV) Micropyle. At the tip the integuments leave a small opening, the micropyle, through which the pollen tube usually enters.
(D) Basal part of ovule — this matches (II) Chalaza. The chalaza is the end opposite the micropyle, the base of the ovule.
NCERT Extract:
The Pistil, Megasporangium (ovule) and Embryo Sac – “… The ovule is a small structure attached to the placenta by means of a stalk called funicle. The body of the ovule fuses with funicle in the region called hilum. Thus, hilum represents the junction between ovule and funicle. Each ovule has one or two protective envelopes called integuments. Integuments encircle the nucellus except at the tip where a small opening called the micropyle is organised. Opposite the micropylar end, is the chalaza, representing the basal part of the ovule.”
