Endosperm of angiosperms is produced after fertilization of a male gamete with

Options

A. Polar nuclei
B. Antipodal cell
C. Synergid
D. Egg cell

Answer

To answer the question about the production of endosperm in angiosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Double Fertilization**:
- In angiosperms, a unique process called double fertilization occurs. This involves the fusion of two male gametes with different female structures.

2. **Pollen Tube Function**:
- When pollen grains land on the stigma of a flower, they germinate and form a pollen tube. This tube carries two male gametes to the ovule.

3. **Fertilization Events**:
- One male gamete fertilizes the egg cell, leading to the formation of a diploid zygote.
- The second male gamete fuses with the central cell, which contains two polar nuclei.

4. **Formation of Endosperm**:
- The fusion of the second male gamete with the two polar nuclei results in the formation of a triploid cell, which develops into the endosperm. This endosperm serves as a nutrient source for the developing embryo.

5. **Conclusion**:
- Therefore, the endosperm of angiosperms is produced after the fertilization of a male gamete with the polar nuclei of the central cell.

### Final Answer:
The endosperm of angiosperms is produced after fertilization of a male gamete with the polar nuclei (central cell).
