If all the cells in any gland are secretory, the gland is :

Options

A. Holocrine
B. Apocrine
C. Merocrine
D. Heterocrine

Answer

To determine the type of gland where all the cells are secretory, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Gland**:
- A gland is an organ made up of cells that are specialized for secretion.

2. **Identify the Types of Glands**:
- Glands can be classified into two main categories: endocrine and exocrine.
- Endocrine glands are ductless and secrete hormones directly into the bloodstream, while exocrine glands secrete substances through ducts.

3. **Focus on Secretory Cells**:
- The question specifies that all cells in the gland are secretory. This means that every cell in the gland is involved in the secretion process.

4. **Examine Types of Secretory Glands**:
- There are three types of secretory glands based on their secretion methods:
- **Holocrine**: Entire cells rupture to release their contents.
- **Apocrine**: Portions of the cell are lost during secretion.
- **Merocrine**: Cells secrete their products through exocytosis without losing any part of themselves.

5. **Determine the Correct Type**:
- Since the question states that all cells in the gland are secretory, we need to identify which type of gland fits this description.
- In Holocrine glands, the entire cell is involved in secretion, meaning all cells contribute to the secretion by rupturing.

6. **Conclusion**:
- Therefore, if all the cells in any gland are secretory, that gland is classified as a **Holocrine gland**.

### Final Answer:
The gland is a **Holocrine gland**.
