Internodal elongation just prior to flowering in plants is called as

Options

A. spooling
B. elution
C. bolting
D. botulism

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe internodal elongation that occurs just before flowering in plants.

2. **Identifying Key Terms**: The key terms in the question are "internodal elongation" and "prior to flowering." This indicates we are looking for a specific biological process related to plant growth.

3. **Considering the Options**: The options provided are pooling, elution, bolting, and botulism. We need to determine which of these terms is related to internodal elongation.

4. **Recalling Relevant Information**: It is known that certain hormones in plants, such as gibberellins, promote growth and elongation. Specifically, gibberellins are associated with the process of bolting.

5. **Defining Bolting**: Bolting is defined as the rapid elongation of the stem (internodal elongation) that occurs in some plants as they prepare to flower. This process is crucial for ensuring that the flowers are positioned for effective pollination.

6. **Identifying the Hormone**: The hormone responsible for this internodal elongation is gibberellin, which promotes the growth of the plant and is often referred to as the "bolting hormone."

7. **Conclusion**: Therefore, the correct answer to the question is "bolting," which refers to the internodal elongation just prior to flowering in plants.

**Final Answer**: Bolting
