How many haploid cells are present in a mature female gametophyte of a flowering plant ?

Options

A. six
B. eight
C. seven
D. five

Answer

To determine how many haploid cells are present in a mature female gametophyte of a flowering plant, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Female Gametophyte**:
The mature female gametophyte, also known as the embryo sac, is a structure found within the ovule of flowering plants.

2. **Identify the Types of Cells Present**:
In the mature female gametophyte, there are several types of cells:
- **Antipodal Cells**: There are three antipodal cells located at the chalazal end of the embryo sac.
- **Synergids**: There are two synergid cells located near the egg cell.
- **Egg Cell**: There is one egg cell.

3. **Count the Haploid Cells**:
- The three antipodal cells are haploid.
- The two synergid cells are haploid.
- The one egg cell is also haploid.
- Therefore, the total number of haploid cells can be calculated as follows:
- Antipodal cells: 3
- Synergids: 2
- Egg cell: 1
- Total haploid cells = 3 (antipodal) + 2 (synergids) + 1 (egg) = 6 haploid cells.

4. **Conclusion**:
The total number of haploid cells present in a mature female gametophyte of a flowering plant is **6**.

### Final Answer:
The answer is **6 haploid cells**.
