Simple epithelium is a tissue in which cells are

Options

A. hardened and provide support to the organ
B. cemented directly to one another to form a single layer
C. continuously dividing to provide form to an organ
D. loosely connected to one another to form an irregular organ

Explanation

### Step-by-Step Text Solution:

1. **Definition of Simple Epithelium**: Simple epithelium is a type of epithelial tissue that consists of a single layer of cells. This means that all the cells are arranged in one continuous layer.

2. **Characteristics of Simple Epithelium**: The cells in simple epithelium are closely packed together. They are cemented directly to one another, which helps to form a barrier that can protect underlying tissues.

3. **Connection to Basement Membrane**: The cells of simple epithelium are in direct contact with the basement membrane. The basement membrane is a thin layer that supports the epithelium and separates it from the underlying connective tissue.

4. **Function of Simple Epithelium**: Simple epithelium primarily functions in absorption, secretion, and filtration. It allows for the efficient exchange of materials due to its thin structure.

5. **Types of Simple Epithelium**: There are three main types of simple epithelium based on cell shape:
- **Simple Squamous Epithelium**: Flat and thin cells.
- **Simple Cuboidal Epithelium**: Cube-shaped cells.
- **Simple Columnar Epithelium**: Tall and column-like cells.

6. **Conclusion**: In summary, simple epithelium is a tissue in which cells are cemented directly to one another to form a single layer.
