Which of the following shows plasticity?

Options

A. Larkspur
B. Buttercup
C. Cotton
D. All are correct

Answer

To solve the question "Which of the following shows plasticity?", we need to understand the concept of plasticity in plants.

### Step-by-Step Solution:

1. **Understanding Plasticity**:
- Plasticity refers to the ability of an organism, particularly plants, to change their structure or form in response to environmental conditions or different phases of life.

2. **Identifying Examples**:
- One of the key examples of plasticity in plants is known as **heterophylly**. This phenomenon occurs when a single plant produces different types of leaves at different stages of its life or in response to varying environmental conditions.

3. **Examples of Heterophylly**:
- Plants such as **Larkspur**, **Buttercup**, and **Cotton** exhibit heterophylly. For instance, juvenile leaves of these plants may differ significantly in shape from mature leaves, or leaves may vary depending on whether the plant is in a terrestrial or aquatic habitat.

4. **Conclusion**:
- Based on the explanation and examples provided, we can conclude that the plants mentioned (Larkspur, Buttercup, and Cotton) show plasticity through the phenomenon of heterophylly. Therefore, the correct answer to the question is option number 4.
