Answer

**Step-by-Step Solution:**

1. **Understanding Guard Cells**: Guard cells are specialized cells that surround the stomata (the pores) in the leaves of plants. They play a crucial role in regulating the opening and closing of these stomata.

2. **Structure of Guard Cells**: These cells are typically kidney-shaped and are found in pairs. They work together to control the size of the stomatal opening.

3. **Presence of Chloroplasts**: Guard cells contain chloroplasts, which are the organelles responsible for photosynthesis.

4. **Role of Chlorophyll**: Chloroplasts contain chlorophyll, the green pigment that is essential for photosynthesis. This pigment is what gives the green color to plants.

5. **Conclusion about Color**: Since guard cells contain chloroplasts with chlorophyll, they are green in color. Therefore, the correct answer to the question is that guard cells are green.

**Final Answer**: Guard cells are green in color.
