Which of the following is an example of unicellular glandular cells?

Options

A. Cells of salivary gland
B. Goblet cells alimentary canal
C. Cells of inner lining of ducts of salivary glands
D. Cells on the moist surface of buccal cavity

Answer

To solve the question of identifying an example of unicellular glandular cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Unicellular**: Refers to organisms or cells that consist of a single cell.
- **Glandular Cells**: Cells that are specialized for secretion.

2. **Analyze the Options**:
- We need to evaluate each option provided to see if they are unicellular and glandular.

3. **Evaluate the First Option (Cells of Salivary Gland)**:
- The cells of the salivary gland are part of a multicellular structure. They are not unicellular as they form a complex gland.

4. **Evaluate the Second Option (Goblet Cells)**:
- Goblet cells are found in the alimentary canal. They are cup-shaped and secrete mucin, which forms a protective covering. Since they are made of a single cell, they are classified as unicellular glandular cells.

5. **Evaluate the Third Option (Cells of Inner Lining of Ducts of Salivary Gland)**:
- These cells are part of a compound epithelium, which is a multicellular structure. Therefore, they are not unicellular.

6. **Evaluate the Fourth Option (Cells on the Moist Surface of Buccal Cavity)**:
- The cells here are cuboidal epithelial cells that form a multicellular structure. They serve protective functions but are not unicellular.

7. **Conclusion**:
- After evaluating all options, the only unicellular glandular cell is the **Goblet Cell**.

### Final Answer:
The correct answer is **Goblet Cells**.
