The difference in shapes of leaves produced in air and those produced in water is seen in

Options

A. cotton
B. coriander
C. larkspur
D. buttercup

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the difference in shapes of leaves produced in air versus those produced in water. This phenomenon is related to how plants adapt to their environments.

2. **Identifying the Phenomenon**: The concept that explains the ability of plants to form different structures based on their environment is called "plasticity." This includes the ability to produce different leaf shapes depending on whether the plant is in a terrestrial (air) or aquatic (water) environment.

3. **Exploring Heterophylly**: The specific type of plasticity that refers to the production of different leaf shapes in different environments is known as "heterophylly." Heterophylly can occur due to different growth phases (juvenile vs. adult leaves) or due to environmental conditions (terrestrial vs. aquatic).

4. **Analyzing the Options**:
- **Cotton**: Generally does not show significant heterophylly based on environment.
- **Coriander**: Primarily has similar leaf shapes regardless of environment.
- **Luxper**: Exhibits heterophylly based on different phases (juvenile vs. adult leaves).
- **Buttercup**: Known for showing different leaf shapes in terrestrial versus aquatic environments.

5. **Conclusion**: Based on the analysis, the correct answer to the question about the difference in shapes of leaves produced in air and those produced in water is **Buttercup** (Option D).
