The first cell of sporophyte in angiosperm is

Options

A. Pollen grain
B. Megaspore
C. Zygote
D. Microspore

Answer

To answer the question "The first cell of sporophyte in angiosperm is," we need to understand the life cycle of angiosperms and the role of the sporophyte. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Sporophyte**:
- The sporophyte is the diploid (2N) phase of the plant life cycle. It develops from the zygote after fertilization.

2. **Formation of Zygote**:
- In angiosperms, the life cycle begins with the fusion of male and female gametes. The male gamete (sperm) from the pollen grain fuses with the female gamete (egg) in the ovule.
- This fusion results in the formation of a zygote, which is the first cell of the sporophyte.

3. **Characteristics of the Zygote**:
- The zygote is diploid (2N) because it contains genetic material from both the male and female gametes.
- It is the initial cell that will undergo multiple divisions and develop into the sporophyte.

4. **Development of Sporophyte**:
- After the zygote is formed, it develops into a sporophyte embryo and eventually grows into a mature sporophyte.

5. **Conclusion**:
- Therefore, the first cell of the sporophyte in angiosperms is the zygote.

### Final Answer:
The first cell of sporophyte in angiosperm is the **Zygote**.
