Which one of the following would occur during bolting?

Options

A. Uptake of water
B. Elongation of internodes
C. Uptake of mineral salts
D. Extension of lamina

Answer

To solve the question "Which one of the following would occur during bolting?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Bolting**:
- Bolting is a process that occurs in certain plants, particularly biennial plants, where there is a rapid elongation of the flowering stem. This typically happens before the plant flowers and produces seeds.

2. **Identifying the Purpose of Bolting**:
- The primary purpose of bolting is to enhance reproduction by allowing the plant to grow taller and produce flowers and seeds more effectively.

3. **Analyzing the Options**:
- The options given are:
a. Uptake of water
b. Elongation of internodes
c. Uptake of mineral salts
d. Extension of lamina

4. **Evaluating Each Option**:
- **Uptake of water**: While plants do take up water, this is not a specific characteristic of bolting.
- **Elongation of internodes**: This is a key feature of bolting, as the internodes (the segments of the stem between the leaves) elongate significantly during this process.
- **Uptake of mineral salts**: Similar to water uptake, this is a general plant function and not specific to bolting.
- **Extension of lamina**: This refers to the expansion of the leaf blade, which is not directly related to the bolting process.

5. **Conclusion**:
- Based on the analysis, the correct answer is **elongation of internodes**, as this is the primary occurrence during the bolting process.

### Final Answer:
**Elongation of internodes**
