Connective tissue differs from epithelial tissue in having  

Options

A. basement membrane
B. large extracellular matrix
C. cells arranged apart from each other
D. both 2 & 3

Answer

**Step-by-Step Solution:**

1. **Understanding the Tissues**: Begin by identifying the two types of tissues in question: connective tissue and epithelial tissue.

2. **Key Characteristics of Connective Tissue**:
- Connective tissue has a significant amount of extracellular matrix, which is the material outside the cells that provides structural and biochemical support.
- The cells in connective tissue are scattered and not tightly packed together.
- Connective tissue contains blood vessels, which are essential for nutrient and waste exchange.

3. **Key Characteristics of Epithelial Tissue**:
- Epithelial tissue is characterized by closely packed cells that form continuous sheets or layers.
- There is little to no extracellular matrix in epithelial tissue.
- Epithelial tissue lacks blood vessels; it receives nutrients through diffusion from underlying connective tissue.

4. **Comparing the Two Tissues**:
- One of the main differences is the presence of a large extracellular matrix in connective tissue, while epithelial tissue has minimal extracellular matrix.
- Connective tissue cells are arranged apart from each other, while epithelial tissue cells are tightly packed.

5. **Identifying the Correct Answer**: Based on the differences outlined, the correct answer to the question "Connective tissue differs from epithelial tissue in having" is option 4, which includes both the presence of a large extracellular matrix and the arrangement of cells being apart from each other.

**Final Answer**: Connective tissue differs from epithelial tissue in having a large extracellular matrix and cells that are arranged apart from each other (Option 4).
