Match the structures in the Angiospermic embryosac in List I with...
Match the structures in the Angiospermic embryosac in List I with their correct ploidy levels in List II.
Choose the correct answer from the options given below:
| List I (Structures in the Angiospermic embryosac) | List II (Ploidy levels) |
|---|---|
| (A). Definitive nucleus | (I). n |
| (B). Synergid | (II). 3n |
| (C). Primary Endosperm Nucleus | (III). 2n |
Options
- A(A) - (I), (B) - (II), (C) - (III).
- B(A) - (III), (B) - (I), (C) - (II).
- C(A) - (II), (B) - (III), (C) - (I).
- D(A) - (III), (B) - (II), (C) - (I).
Correct answer
B. (A) - (III), (B) - (I), (C) - (II).
Step-by-step solution
The definitive nucleus, also known as the secondary nucleus, is formed by the fusion of two haploid polar nuclei before fertilization. Thus, its ploidy level is .
Synergids are cells present in the egg apparatus of the embryo sac and are formed by mitotic divisions of the functional megaspore. Thus, their ploidy level is .
The Primary Endosperm Nucleus (PEN) is formed during double fertilization by the fusion of a haploid male gamete (n). Thus, its ploidy level is .
Therefore, the correct matching is (A) - (III), (B) - (I), (C) - (II).
Answer: (A) - (III), (B) - (I), (C) - (II).
Synergids are cells present in the egg apparatus of the embryo sac and are formed by mitotic divisions of the functional megaspore. Thus, their ploidy level is .
The Primary Endosperm Nucleus (PEN) is formed during double fertilization by the fusion of a haploid male gamete (n). Thus, its ploidy level is .
Therefore, the correct matching is (A) - (III), (B) - (I), (C) - (II).
Answer: (A) - (III), (B) - (I), (C) - (II).
