Water secreting glands also called by hydath-odes are found along the margin of leaves in

Options

A. hibiscus
B. trapaeolum
C. eucalyptus
D. nerium

Answer

**Step-by-Step Solution:**

1. **Understanding Hydathodes**: Hydathodes are specialized structures in plants that secrete water. They are often found at the edges or margins of leaves.

2. **Identifying the Plant Family**: The question specifies that hydathodes are found in a particular plant family. The family in question is Nasturtium, which is known for having these water-secreting glands.

3. **Characteristics of Nasturtium**: Nasturtium (genus Tropaeolum) has leaves that are shaped in a way that allows water to accumulate at the margins. This is an exclusive feature of this plant.

4. **Comparison with Other Plants**: The question also mentions other plants such as Hibiscus, Eucalyptus, and Nerium. While these plants may have similar leaf shapes, they do not have hydathodes that function in the same way as those in Nasturtium.

5. **Conclusion**: Based on the information, the correct answer is that water-secreting glands (hydathodes) are found along the margin of leaves in the plant family Nasturtium.

**Final Answer**: Water secreting glands (hydathodes) are found along the margin of leaves in Nasturtium.
