In Coconut, hydrochory occurs due to presence of

Options

A. Papery epicarp
B. Fibrous mesocarp
C. Stony endocarp
D. Liquid endosperm

Answer

**Step-by-Step Solution:**

1. **Understanding Hydrochory**: Hydrochory is the process of seed or fruit dispersal by water. The term "hydro" refers to water, indicating that water is the medium through which the seeds or fruits are transported.

2. **Identifying the Structure of Coconut**: The coconut fruit consists of three main layers:
- **Epicarp**: The outermost layer of the fruit.
- **Mesocarp**: The middle layer, which is fibrous in the case of coconuts.
- **Endocarp**: The innermost layer, which is hard and stony.

3. **Analyzing the Role of Mesocarp**: The mesocarp of the coconut is fibrous, which contributes to the buoyancy of the fruit. This buoyancy allows the coconut to float on water.

4. **Connecting Buoyancy to Hydrochory**: Since the fibrous mesocarp enables the coconut to float, it facilitates the dispersal of the coconut seeds via water. When coconuts fall into the ocean or rivers, they can travel long distances before reaching a suitable location for germination.

5. **Conclusion**: Therefore, the presence of the fibrous mesocarp is crucial for hydrochory in coconuts, as it allows them to float and be dispersed by water.

**Final Answer**: In coconut, hydrochory occurs due to the presence of the fibrous mesocarp.
