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 zygote in this process. Here is a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Life Cycle of Angiosperms**:
- Angiosperms, or flowering plants, exhibit a diploid life cycle. This means that the dominant phase of their life cycle is the sporophytic phase, which is diploid (2n).

2. **Gametogenesis Process**:
- In angiosperms, gametes are formed through a process called gametogenesis, which involves meiosis. This results in the formation of haploid (n) gametes.

3. **Fertilization (Syngamy)**:
- The male and female gametes fuse during fertilization, a process known as syngamy. This fusion results in the formation of a diploid zygote.

4. **Formation of the First Sporophytic Cell**:
- The zygote is the first cell of the sporophyte generation in angiosperms. It is the result of the fusion of the male and female gametes and marks the beginning of the sporophytic phase.

5. **Transition to Sporophyte**:
- After the zygote is formed, it undergoes mitotic divisions and develops into the sporophyte, which is the mature plant.

### Conclusion:
The first cell of the sporophyte in angiosperms is the **zygotic cell**.
