If you squeeze a seed of orange you might observe many embryos of different sizes. It is because of :

Options

A. Polyembryony
B. Apomixis
C. Pollination
D. Parthenocarpy

Answer

To solve the question regarding why squeezing an orange seed reveals many embryos of different sizes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks why multiple embryos of different sizes can be observed when squeezing an orange seed.

2. **Identifying Key Terms**: The key term here is "embryos" and the context of their occurrence in seeds.

3. **Exploring Options**:
- **Polyembryony**: This is the phenomenon where more than one embryo develops from a single fertilized ovule. In some plants, including oranges, this can lead to multiple embryos within a single seed.
- **Apomixes**: This refers to the formation of seeds without fertilization. This does not explain the presence of multiple embryos.
- **Pollination**: This is the transfer of pollen from the male anther to the female stigma. It does not relate to the number of embryos in a seed.
- **Parthenocarpy**: This is the development of fruit without fertilization, which again does not explain multiple embryos.

4. **Analyzing the Correct Answer**: Given the definitions and explanations, polyembryony is the only option that explains the presence of multiple embryos of different sizes in the orange seed.

5. **Conclusion**: Therefore, the correct answer to the question is that the presence of many embryos of different sizes when squeezing an orange seed is due to **polyembryony**.

### Final Answer:
The correct answer is **polyembryony**.
