Grafting is not possible in monocots because of

Options

A. Lack of cambium
B. Presence of scattered vascular bundles
C. Parallel venation
D. Herbaceous nature

Answer

### Step-by-Step Solution:

1. **Understanding Grafting**: Grafting is a horticultural technique where tissues from one plant are inserted into those of another so that they may grow together. This process requires certain anatomical features in the plants involved.

2. **Identifying Plant Types**: Plants are broadly classified into two categories: monocots and dicots. Monocots include plants like grasses and lilies, while dicots include plants like roses and oak trees.

3. **Key Anatomical Feature**: One of the critical anatomical features needed for successful grafting is the presence of cambium. Cambium is a type of meristematic tissue that is responsible for the secondary growth of plants.

4. **Cambium in Monocots vs. Dicots**: In dicots, the cambium is present in the vascular bundles, allowing for the formation of new tissues during grafting. However, in monocots, cambium is typically absent.

5. **Conclusion**: Due to the absence of cambium in monocots, they lack the necessary regenerative capacity to form new tissues after grafting. This is why grafting is not possible in monocots.

6. **Final Answer**: The correct reason why grafting is not possible in monocots is **the lack of cambium**.
