Hooks help in fruit dispersal of

Options

A. Martynia
B. Heritiera
C. Viscum
D. Colutea

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which plant's fruit dispersal mechanism involves hooks. We need to identify the correct option among Martinia, Heritiera, Viscum, and Collutae.

2. **Defining Fruit Dispersal Mechanisms**: Fruit dispersal can occur through various mechanisms, one of which is zoochory. Zoochory is the dispersal of seeds and fruits by animals.

3. **Identifying the Role of Hooks**: In zoochory, certain fruits and seeds have adaptations such as hooks, spines, or bristles that allow them to attach to the fur or feathers of animals. This attachment helps in the movement of seeds to new locations.

4. **Analyzing the Options**:
- **Martinia**: This plant has fruits with hooks that can attach to animals, making it a candidate for this question.
- **Heritiera**: This plant does not have such adaptations for dispersal by hooks.
- **Viscum**: Similar to Heritiera, Viscum does not utilize hooks for dispersal.
- **Collutae**: This option also does not involve hooks for dispersal.

5. **Conclusion**: Based on the analysis, the correct answer is **Martinia**, as it utilizes hooks for dispersal through the zoochory mechanism.

### Final Answer:
The correct answer is **A) Martinia**.
