Green cells of epidermis are

Options

A. Bulliform cells
B. Subsidiary cells
C. motor cells
D. guard cells

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the "green cells of epidermis." We need to identify which type of cell in the epidermis of a plant is green in color.

2. **Identifying the Options**: The options provided are:
- A) Buliform cells
- B) Subsidiary cells
- C) Motor cells
- D) Guard cells

3. **Analyzing the Epidermis**: The epidermis of a leaf is covered by a waxy layer called the cuticle, which helps in preventing water loss.

4. **Identifying the Function of Cells**:
- **Buliform cells**: These cells are involved in the folding and unfolding of leaves, but they do not contain chlorophyll and are not green.
- **Subsidiary cells**: These cells support guard cells but are not typically green themselves.
- **Motor cells**: This term is not commonly used in the context of plant anatomy.
- **Guard cells**: These are specialized cells that surround the stomatal pores and are responsible for regulating gas exchange. They contain chloroplasts, which means they have chlorophyll, giving them a green color.

5. **Conclusion**: Based on the analysis, the green cells of the epidermis are the **guard cells**. They are located in the epidermis of leaves and are responsible for controlling the opening and closing of stomata.

### Final Answer:
The green cells of the epidermis are **guard cells**.
