Epidermal cells containing chloraplasts are

Options

A. Hydathode
B. Stomata
C. Guard cell
D. Epithem

Answer

**Step-by-Step Solution:**

1. **Understanding Epidermal Cells**: Epidermal cells are the outermost layer of cells in plants, which serve as a protective barrier against environmental factors. They are found on various parts of the plant, including leaves, stems, and roots.

2. **Identifying the Options**: The question provides four options: Hydrothoid, Stomata, Guard Cell, and Epithelium. We need to determine which of these contains chloroplasts.

3. **Analyzing Hydrothoid**: Hydrothoid cells are specialized structures found in some aquatic plants that help in the secretion of water. They do not contain chloroplasts and are not involved in photosynthesis.

4. **Analyzing Stomata**: Stomata are small openings on the surface of leaves that facilitate gas exchange and transpiration. They themselves do not contain chloroplasts, but they are surrounded by guard cells.

5. **Analyzing Guard Cells**: Guard cells are specialized epidermal cells that surround each stoma. They are responsible for regulating the opening and closing of stomata. Importantly, guard cells do contain chloroplasts, which allow them to perform photosynthesis and generate the energy needed for their function.

6. **Conclusion**: Based on the analysis, the correct answer to the question is that epidermal cells containing chloroplasts are **Guard Cells**.

**Final Answer**: Guard Cells
