Give an example of plasticity.

Explanation

### Step-by-Step Solution

1. **Understanding Plasticity**: Plasticity in biology refers to the ability of an organism to change its morphology or physiology in response to environmental conditions. In plants, this is often observed in their growth patterns.

2. **Example of Plasticity in Plants**: A clear example of plasticity can be seen in the leaves of plants. Depending on the environmental conditions, such as light availability, leaves can exhibit different growth characteristics.

3. **Leaf Adaptations**:
- **Size and Shape**: Leaves may grow thicker and longer in size when there is ample sunlight. This adaptation helps maximize photosynthesis.
