Plasticity refers to

Options

A. Ability of the plants to undergo different pathways of metabolism suitable to the environments
B. Ability to exhibit different phase of life to produce different types of structures
C. Ability of plants to grow through out their life
D. 1 & 2

Answer

**Step-by-Step Solution:**

1. **Understanding Plasticity**: Plasticity in plants refers to their ability to adapt and change in response to different environmental conditions or stages of growth. This means that plants can exhibit various forms and structures based on their surroundings or developmental phases.

2. **Analyzing the Options**: The question provides four options regarding what plasticity refers to:
- Option 1: Ability of plants to undergo different pathways of metabolism suitable to environments.
- Option 2: Ability to exhibit different phases of life to produce different types of structures.
- Option 3: Ability of plants to grow throughout their life.
- Option 4: Both option one and option two.

3. **Evaluating Each Option**:
- **Option 1** is correct because plants can adapt their metabolic pathways based on environmental conditions (e.g., terrestrial vs. aquatic plants).
- **Option 2** is also correct as plants can exhibit different structures at various life stages (e.g., juvenile vs. mature leaves).
- **Option 3** is incorrect because while plants can grow for a long time, they do not grow indefinitely throughout their entire life.
- **Option 4** combines the correct options (1 and 2), making it the best choice.

4. **Conclusion**: The correct answer to the question is Option 4, which states that plasticity refers to both the ability of plants to undergo different metabolic pathways suitable to environments and the ability to exhibit different phases of life to produce different types of structures.

**Final Answer**: Option 4 (Both option one and option two).
