Rejuvenation of growth of cut grass is accomplished by

Options

A. Apical meristems
B. Intercalary meristems
C. Lateral meristems
D. Cylindrical meristems

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the rejuvenation of growth in cut grass and which type of meristem is responsible for this process.

2. **Identifying Types of Meristems**:
- **Apical Meristems**: These are located at the tips of roots and shoots and are responsible for the primary growth of the plant.
- **Intercalary Meristems**: These are found at the base of leaves or internodes and are responsible for the growth of grass and other monocots after cutting.
- **Lateral Meristems**: These contribute to the secondary growth of plants, increasing their thickness.
- **Cylindrical Meristems**: This term is less commonly used and may refer to lateral meristems.

3. **Analyzing the Role of Apical Dominance**: When the tips of grass (which contain apical meristems) are cut, the apical dominance is removed. This allows other parts of the plant to grow more freely.

4. **Focusing on Intercalary Meristems**: After cutting the grass, the intercalary meristems become active. These meristems allow for regrowth at the base of the grass blades, leading to rejuvenation.

5. **Conclusion**: The rejuvenation of growth of cut grass is primarily accomplished by intercalary meristems, as they are responsible for the regrowth after the apical dominance is removed.

### Final Answer:
The rejuvenation of growth of cut grass is accomplished by **intercalary meristems**.
