The leaves of juvenile plant differ in shape from those of mature plant in

Options

A. Delphinium
B. Tamarindus
C. pineapple
D. tomato

Answer

### Step-by-Step Solution:

1. **Understanding Juvenile and Mature Plants**:
- Juvenile plants are young and do not flower, while mature plants are in the reproductive phase and can produce flowers.

2. **Concept of Heterophylly**:
- Heterophylly refers to the phenomenon where a plant exhibits different leaf shapes at different stages of its life cycle. This is common in certain species as they transition from juvenile to mature forms.

3. **Example of Heterophylly**:
- A specific example of heterophylly is found in the plant Delphinium nudicaule, commonly known as red larkspur. In its juvenile stage, the leaves have a distinct shape compared to the leaves in the mature stage.

4. **Visual Comparison**:
- In the juvenile stage, the leaves of Delphinium are different in shape compared to the mature stage. This change in leaf shape is a clear indicator of the plant's transition from juvenile to mature.

5. **Identifying the Correct Option**:
- Given the options provided, the plant that exhibits different leaf shapes in juvenile and mature stages is Delphinium nudicaule (option 1). The other options do not demonstrate this characteristic.

### Final Answer:
The leaves of juvenile plants differ in shape from those of mature plants due to the phenomenon of heterophylly, as exemplified by Delphinium nudicaule.
