Identify the correct statement

Options

A. Because of marked climatic variations, plants growing near the sea shore do not produce annual rings
B. The age of the plant can be determined by its height
C. Grafting is difficult in monocot plants as they have scattered vascular bundles
D. Healing of damaged tissue is because of activity of sclerenchyma cells.

Answer

To identify the correct statement from the options provided, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Evaluate Statement 1**: "Because of the marked climatic variation, plants growing near the seashore do not produce annual rings."
- **Analysis**: This statement is incorrect. Annual rings are produced in trees regardless of climatic variations. They are a result of seasonal growth patterns and are present in many plants, particularly woody plants.

2. **Evaluate Statement 2**: "The age of the plant can be determined by its height."
- **Analysis**: This statement is also incorrect. The age of a plant is not accurately determined by its height, as different species grow at different rates. The age is more accurately determined by counting the annual rings in the stem or trunk of the plant.

3. **Evaluate Statement 3**: "Grafting is difficult in monocot plants because they have scattered vascular bundles."
- **Analysis**: This statement is correct. Monocots lack cambium tissue, which is essential for the grafting process. The scattered vascular bundles in monocots make it difficult for grafting to occur, as there is no cambium layer to facilitate the healing and joining of tissues.

4. **Evaluate Statement 4**: "The healing of damaged tissue is because of the activity of sclerenchyma cells."
- **Analysis**: This statement is incorrect. Sclerenchyma cells are dead cells that provide structural support and do not participate in the healing of damaged tissues. Healing typically involves living cells, such as parenchyma or cambium cells.

### Conclusion:
After evaluating all the statements, the correct statement is **Statement 3**: "Grafting is difficult in monocot plants because they have scattered vascular bundles."
