The correct answer is Option (4)- A - 4, B - 3, C - 2, D - 1
| Column I. |
Column II. |
| A. Antipodal |
4. n |
| B. Central cell |
3. (n + n) |
| C. MMC |
2. 2n |
| D. Endosperm |
1. 3n |
A. Antipodal - 4. n
Antipodal cells are part of the female gametophyte in flowering plants and are typically haploid (n).
B. Central cell - 3. (n + n)
The central cell in the embryo sac of flowering plants contains two haploid nuclei (n + n) before fertilization.
C. MMC (Megaspore Mother Cell) - 2. 2n
The Megaspore Mother Cell (MMC) is diploid (2n) and undergoes meiosis to form haploid megaspores.
D. Endosperm - 1. 3n
The endosperm in flowering plants is typically triploid (3n), formed by the fusion of a sperm nucleus (n) with two polar nuclei (n + n) during fertilization. |
