Which of the following lies in the central cell

Options

A. Two polar nuclei
B. Disintegrating tube nucleus & synergid nucleus
C. Filiform apparatus
D. Two male nuclei

Answer

### Step-by-Step Solution:

1. **Understanding the Structure**: The question asks about the central cell, which is a part of the female gametophyte, specifically within the embryo sac.

2. **Identifying the Components**: In the mature embryo sac, we have several components:
- Three antipodal cells located at the chalazal end.
- An egg apparatus at the micropylar end, consisting of one egg cell and two synergids.
- The central cell, which is located in the middle of the embryo sac.

3. **Characteristics of the Central Cell**: The central cell is the largest cell in the embryo sac and contains two polar nuclei. Each of these polar nuclei is haploid (N), making the central cell a diploid structure (N + N).

4. **Evaluating the Options**: The question likely provides multiple options regarding what lies in the central cell. Based on the understanding that the central cell contains two polar nuclei, we can conclude that:
- The correct answer is that the central cell contains two polar nuclei (N + N).
- Other options such as the degenerated tube nucleus, synergid nucleus, or filiform apparatus do not belong to the central cell.

5. **Final Answer**: Therefore, the correct answer to the question "Which of the following lies in the central cell?" is the two polar nuclei.
