Choose the incorrect statement w.r.t epithelium tissue

Options

A. Basement membrane anchors the epithelium to the underlying connective tissue
B. Basement membrane is a cellular layer
C. Microvilli present on the free apical surface of cells, increase the absorptive surface area
D. Ducts of glands are mostly lined by simple cuboidal epithelium

Answer

To solve the question of identifying the incorrect statement regarding epithelial tissue, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Epithelial Tissue**:
Epithelial tissue is a type of tissue that covers body surfaces, lines cavities and organs, and forms glands. It consists of closely packed cells with minimal intercellular matrix.

**Hint**: Remember that epithelial tissue is primarily about cell arrangement and function.

2. **Examine the Statements**:
We have four statements to analyze. We need to determine which one is incorrect.

3. **Statement 1**: "Basement membrane anchors the epithelium to the underlying connective tissue."
- This statement is **correct**. The basement membrane is a thin layer that provides support and anchors epithelial cells to the underlying connective tissue.

**Hint**: Think about the role of the basement membrane in tissue structure.

4. **Statement 2**: "Basement membrane is a cellular layer."
- This statement is **incorrect**. The basement membrane is not made up of cells; rather, it is composed of fibrous proteins and acts as a support structure for epithelial cells.

**Hint**: Recall the composition of the basement membrane and its distinction from cellular structures.

5. **Statement 3**: "Microvilli present on free apical surface of cells increase the absorptive surface area."
- This statement is **correct**. Microvilli are tiny projections that increase the surface area for absorption, commonly found in the intestines.

**Hint**: Consider where microvilli are typically found and their function.

6. **Statement 4**: "Ducts of glands are lined by simple cuboidal epithelium."
- This statement is **correct**. Simple cuboidal epithelium, consisting of a single layer of cube-shaped cells, is indeed found lining the ducts of glands.

**Hint**: Think about the structure of glandular tissues and their epithelial lining.

### Conclusion:
The incorrect statement regarding epithelial tissue is **Statement 2**: "Basement membrane is a cellular layer."
