Appearance of vegetative propagules from the nodes of plant such as sugarcane and ginger is mainly because

Options

A. nodes are shorter than internodes
B. nodes have meristematic cells
C. nodes are located near the soil
D. nodes have non-photosynthetic cells

Answer

To solve the question regarding the appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Vegetative Propagation**:
- Vegetative propagation is a form of asexual reproduction in plants where new individuals arise from vegetative parts such as stems, roots, or leaves.

2. **Identifying the Role of Nodes**:
- In plants like sugarcane and ginger, vegetative propagules (like buds) appear at the nodes. Nodes are the points on a stem where leaves and branches originate.

3. **Analyzing the Options**:
- **Option A**: Nodes are shorter than internodes - This is not a reason for the appearance of propagules.
- **Option B**: Nodes have meristematic cells - This is a key point. Meristematic cells are undifferentiated cells that can divide and differentiate into various types of tissues.
- **Option C**: Nodes are located near the soil - While proximity to soil can help in rooting, it does not explain the formation of propagules.
- **Option D**: Nodes have non-photosynthetic cells - This is irrelevant to the formation of propagules.

4. **Conclusion**:
- The correct answer is **Option B**: The appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because nodes have meristematic cells. These cells are capable of division and can differentiate into various tissues, leading to the formation of new plants.
