Hydathode has

Options

A. Subsidiary cells
B. Accessory cell
C. Complementary cells
D. Epithem

Answer

**Step-by-Step Solution:**

1. **Understanding Hydathodes**: Hydathodes are specialized structures found in plants that facilitate the release of water. They are typically located at the edges or tips of leaves.

2. **Identifying the Type of Cells**: The primary type of cells associated with hydathodes are known as epithem cells. These cells are characterized by their loose arrangement.

3. **Location of Epithem Cells**: Epithem cells are specifically located at the dead ends of the vascular veins in leaves. This positioning allows them to effectively manage water movement.

4. **Function of Hydathodes**: The main function of hydathodes is to allow water to ooze out from the plant. This process occurs under certain conditions, particularly when there is excess water in the plant.

5. **Process of Guttation**: The water that is released through hydathodes is a dilute solution, and this process of water exudation is known as guttation. It occurs due to positive pressure within the plant's vascular system.

6. **Conclusion**: Therefore, hydathodes have epithem cells, which facilitate the process of guttation by allowing water to be released from the plant.

**Final Answer**: Hydathodes have epithem cells.
