Which of the following structures show unlimited growth in plants ?

Options

A. Leaves
B. Flower
C. Fruits
D. Roots

Answer

To determine which structure in plants shows unlimited growth, we can analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Structures**: The options given are leaves, flowers, fruits, and roots. We need to evaluate each of these structures in terms of their growth characteristics.

2. **Evaluate Leaves**:
- Leaves come in various shapes and sizes depending on the species.
- However, they do not exhibit unlimited growth. Once a leaf reaches its mature size, it stops growing.
- **Conclusion**: Leaves do not show unlimited growth.

3. **Evaluate Flowers**:
- Flowers are the reproductive structures of angiosperms and also vary in size and color.
- Similar to leaves, flowers do not continue to grow indefinitely; they reach a certain size and then stop developing.
- **Conclusion**: Flowers do not show unlimited growth.

4. **Evaluate Fruits**:
- Fruits develop from flowers and can vary in size and shape.
- While fruits can grow to a certain size, they also have a limit to their growth once they mature.
- **Conclusion**: Fruits do not show unlimited growth.

5. **Evaluate Roots**:
- Roots are known for their ability to grow indefinitely. They can continue to elongate and branch out as long as there are nutrients and water available in the soil.
- Roots adapt their growth based on environmental conditions, which allows them to exhibit unlimited growth.
- **Conclusion**: Roots show unlimited growth.

6. **Final Answer**: Based on the evaluations, the structure that shows unlimited growth in plants is **roots**.
