Answer

To determine how many nuclei are involved in the process of fertilization in flowering plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fertilization in Flowering Plants**:
- Flowering plants, also known as angiosperms, undergo a process called double fertilization.

2. **Identifying the First Fusion**:
- In the first part of double fertilization, one sperm cell fuses with the egg cell.
- This results in the formation of the zygote, which will develop into the embryo.

3. **Identifying the Second Fusion**:
- In the second part of double fertilization, another sperm cell fuses with the two polar nuclei present in the central cell of the ovule.
- This fusion leads to the formation of the endosperm, which nourishes the developing embryo.

4. **Counting the Nuclei**:
- From the above steps, we can count the nuclei involved:
- 1 nucleus from the egg cell.
- 2 nuclei from the two polar nuclei.
- 2 nuclei from the two sperm cells (one for the zygote and one for the endosperm).
- Therefore, the total number of nuclei involved is:
- 1 (egg cell) + 2 (polar nuclei) + 2 (sperm cells) = 5 nuclei.

### Final Answer:
The total number of nuclei involved in the process of fertilization in flowering plants is **5**.
