The ability of a plant to follow different pathways and produce different structures in response to environment is known as

Options

A. Heterophylly
B. Plasticity
C. Effciency index
D. Vernalisation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the ability of plants to adapt and produce different structures in response to environmental changes.

2. **Analyzing the Options:**
- **Heterophyly:** This term refers to the phenomenon where a single plant produces different types of leaves (morphology) at different stages of its life cycle or in response to environmental conditions. However, it is not a broad term for the overall adaptability of plants.
- **Plasticity:** This term refers to the ability of an organism, including plants, to change its morphology, physiology, or development in response to environmental conditions. This is a broader concept that encompasses various adaptations.
- **Efficiency Index:** This term is not commonly used in the context of plant adaptation and does not relate to the ability to produce different structures.
- **Vernalization:** This is a process where certain plants require a period of cold to flower, but it does not refer to the general ability to adapt structurally to the environment.

3. **Identifying the Correct Answer:**
Based on the definitions and explanations of the options, **plasticity** is the correct term that describes the ability of plants to follow different pathways and produce different structures in response to their environment.

4. **Conclusion:**
Therefore, the answer to the question is **plasticity**.
