In which plant heterophyllous development occurs due to environment

Options

A. Coriander
B. Cotton
C. Larkspur
D. Buttercup

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Heterophylly:**
- Heterophylly refers to the phenomenon where a single plant exhibits different types of leaves at different stages of its life cycle or in response to environmental conditions.

2. **Identify the Environmental Influence:**
- In this context, we are looking for a plant that shows heterophylly specifically due to environmental factors, such as growing in different habitats (terrestrial vs. aquatic).

3. **Consider the Options Provided:**
- The options given are buttercup, coriander, cotton, and larkspur. We need to analyze which of these plants shows heterophylly due to environmental conditions.

4. **Analyze the Buttercup Plant:**
- The buttercup plant (genus Ranunculus) is known to exhibit heterophylly. In terrestrial habitats, it develops broad leaves, while in aquatic environments, it produces thin, elongated leaves to adapt to water conditions.

5. **Evaluate Other Options:**
- Coriander, cotton, and larkspur may show variations in leaf shape due to different growth stages (juvenile vs. mature), but they do not exhibit heterophylly as a response to environmental changes like the buttercup does.

6. **Conclude the Answer:**
- Based on the analysis, the plant that exhibits heterophyllous development due to environmental conditions is the buttercup.

**Final Answer:**
- The correct answer is the buttercup (option 4).
