Multicostate divergent reticulate venation is seen in …..leaf

Options

A. Zizyphus
B. Bamboo
C. Castor
D. Mango.

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Multicostate**: This refers to having more than one midrib (principal vein) in the leaf.
- **Divergent**: This means that the major veins of the leaf spread out from a point towards the tip of the leaf.
- **Reticulate Venation**: This refers to an irregular or net-like arrangement of veins in the leaf.

2. **Analyzing the Options**:
- **Ziziphus**: This plant has a multicostate convergent venation, which means the veins converge towards a point rather than diverging. Therefore, it does not fit the criteria.
- **Bamboo**: Bamboo leaves exhibit parallel venation, which is characterized by veins running parallel to each other. This also does not match the required venation type.
- **Mango**: Mango leaves have a unicostate reticulate venation, meaning they have only one midrib and do not fit the multicostate requirement.
- **Castor**: Castor leaves have multicostate divergent reticulate venation. This means they have multiple midribs, the major veins diverge towards the tip, and the arrangement of the veins is irregular.

3. **Conclusion**:
- Based on the analysis, the correct answer is **Castor**, as it exhibits multicostate divergent reticulate venation.

### Final Answer:
The multicostate divergent reticulate venation is seen in **Castor** leaves.
