Heliophytes differ from sciophytes in having

Options

A. Shorter internodes and thicker leaves
B. Longer internodes and thinner leaves
C. Shorter internodes and thinner leaves
D. Longer internodes and thicker leaves.

Answer

To answer the question about how heliophytes differ from sciophytes, we can follow these steps:

### Step-by-Step Solution:

1. **Define Heliophytes**: Heliophytes are plants that thrive in high-intensity sunlight. They are adapted to environments where they receive a lot of light.

2. **Examples of Heliophytes**: Common examples of heliophytes include neem and peepal trees. These plants are well-suited to sunny conditions.

3. **Characteristics of Heliophytes**:
- **Internodes**: Heliophytes typically have shorter internodes. Internodes are the segments of the stem between the leaves.
- **Leaves**: The leaves of heliophytes are generally thicker. This adaptation helps them to retain water and withstand high light intensity.

4. **Define Sciophytes**: Sciophytes, on the other hand, are plants that grow in shaded areas, often under the canopy of other plants. They are adapted to low-light conditions.

5. **Characteristics of Sciophytes**:
- **Internodes**: Sciophytes usually have longer internodes, allowing them to reach towards the light.
- **Leaves**: Their leaves are typically thinner, which helps in maximizing light absorption in low-light environments.

6. **Comparison**:
- Heliophytes have **shorter internodes** and **thicker leaves**.
- Sciophytes have **longer internodes** and **thinner leaves**.

7. **Conclusion**: Based on the characteristics discussed, the correct answer to the question is that heliophytes differ from sciophytes in having **shorter internodes and thicker leaves**.

### Final Answer:
The correct option is **A: shorter internodes and thicker leaves**.
