Match the Column I with Column II.
| Column I | Column II |
|
A. Funicle |
1. Portion below the cotyledon |
|
B. Epicotyl |
2. Portion above the cotyledon |
|
C. Perisperm |
3. Residual nucellus |
|
D. Hypocotyl |
4. Attachment of ovule to the placenta |
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A - 4, B - 2, C - 3, D - 1
(A) Funicle — this matches (4) Attachment of ovule to the placenta. The funicle is the stalk of the ovule. The body of the ovule joins it at the hilum.
(B) Epicotyl — this matches (2) Portion above the cotyledon. In a dicot embryo, the part of the embryonal axis above the cotyledons ends in the plumule (the shoot tip).
(C) Perisperm — this matches (3) Residual nucellus. In some seeds, such as black pepper and beet, part of the nucellus persists in the seed.
(D) Hypocotyl — this matches (1) Portion below the cotyledon. The cylindrical part below the cotyledons ends in the radicle (root tip).
NCERT Extract:
The Megasporangium (Ovule) – “… 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.”
Embryo – “… The portion of embryonal axis above the level of cotyledons is the epicotyl, which terminates with the plumule or stem tip. The cylindrical portion below the level of cotyledons is hypocotyl that terminates at its lower end in the radicle or root tip.”
Seed – “… Occasionally, in some seeds such as black pepper and beet, remnants of nucellus are also persistent. This residual, persistent nucellus is the perisperm.”
