In Angiosperm, formation of endosperm always precedes developments of the ................... .

Options

A. Embryo
B. Zygote
C. Male gametophyte
D. Female gametophyte

Answer

To answer the question "In Angiosperm, formation of endosperm always precedes developments of the ...................", we need to understand the process of fertilization and subsequent development in angiosperms.

### Step-by-Step Solution:

1. **Understanding Angiosperm Fertilization**:
- In angiosperms, fertilization involves the fusion of male and female gametes. The male gamete (pollen) fuses with the female gamete (ovule) to form a zygote.

2. **Formation of Endosperm**:
- After fertilization, the endosperm is formed through a process called double fertilization. One male gamete fuses with the egg cell to form the zygote, while another male gamete fuses with two polar nuclei to form the triploid endosperm.

3. **Role of Endosperm**:
- The endosperm serves as a nutritive tissue that provides essential nutrients to the developing embryo. It is crucial for the growth and development of the embryo.

4. **Development of the Embryo**:
- The development of the embryo begins after the formation of the endosperm. The embryo relies on the endosperm for nourishment during its early stages of development.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the formation of endosperm always precedes the development of the **embryo**.

### Final Answer:
In Angiosperm, formation of endosperm always precedes developments of the **embryo**.
