Adventive reproduction occurs

Options

A. Citrus
B. potato
C. coconut
D. corn

Answer

To answer the question regarding where adventive reproduction occurs, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Adventive Reproduction**: Adventive reproduction, also known as adventive polyembryony, is a form of asexual reproduction where more than one embryo is formed from a single seed. This process does not involve fertilization.

2. **Mechanism of Adventive Reproduction**: In adventive reproduction, the formation of extra embryos occurs due to sporophytic budding. This means that one or more sporophytic cells present in the nucellus or integument of the seed undergo divisions to develop into embryos.

3. **Identifying the Organisms**: We need to identify which of the given options (citrus, potato, coconut, corn) exhibits this type of reproduction.

4. **Analyzing the Options**:
- **Citrus**: Known to exhibit adventive reproduction as it can form multiple embryos from a single seed.
- **Potato**: Primarily reproduces asexually through tubers, not through adventive reproduction.
- **Coconut**: Reproduces sexually through seeds and does not show adventive reproduction.
- **Corn**: Also reproduces sexually and does not exhibit adventive reproduction.

5. **Conclusion**: Based on the analysis, the correct answer is **citrus**, as it is the only option that demonstrates adventive reproduction.

### Final Answer:
Adventive reproduction occurs in **citrus**.
