In flowering plants, post fertilisation events include :-

Options

A. Formation of zygote
B. Embryogenesis
C. Both (1) & (2)
D. Gametogenesis

Answer

To answer the question regarding post-fertilization events in flowering plants, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Post-Fertilization Events**:
- Post-fertilization events refer to the processes that occur after the fertilization of the egg by the sperm in flowering plants.

2. **Formation of Zygote**:
- After fertilization, the male gamete (sperm) fuses with the female gamete (egg cell) to form a diploid zygote. This is the first step in the post-fertilization process.

3. **Embryogenesis**:
- Following the formation of the zygote, the next stage is embryogenesis. This is the process through which the zygote develops into an embryo. It involves multiple cell divisions and differentiation to form the various tissues and organs of the plant.

4. **Identifying Incorrect Options**:
- The question also includes the option of "gametogenesis". It is important to note that gametogenesis is the process of forming gametes (sperm and egg cells), which occurs before fertilization. Therefore, it is not considered a post-fertilization event.

5. **Conclusion**:
- Based on the above points, the correct answer to the question is that post-fertilization events in flowering plants include both the formation of the zygote and embryogenesis.

### Final Answer:
The correct options are:
- Formation of Zygote
- Embryogenesis

Thus, the answer is **both 1 and 2**.
