Modified polysaccharides acting as a ground substance is found in :

Options

A. Epithelial tissue
B. Connective tissue
C. Muscular tissue
D. Neural tissue

Answer

To solve the question regarding the modified polysaccharides acting as a ground substance, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Ground Substance**:
- Ground substance is a component of the extracellular matrix that provides support to tissues. It is primarily composed of modified polysaccharides and proteins.

2. **Identify the Components of Ground Substance**:
- The ground substance consists of complex polysaccharides (like glycoproteins and glycosaminoglycans) and proteins (such as elastin). These components are secreted by fibroblast cells.

3. **Determine the Role of Ground Substance**:
- The main function of ground substance is to provide structural support and facilitate the exchange of nutrients and waste between cells and their environment.

4. **Analyze the Tissue Types Given in the Options**:
- **Epithelial Tissue**: Primarily forms the surface lining of organs and does not contain ground substance.
- **Connective Tissue**: Contains ground substance as part of its extracellular matrix, providing support and connection between different tissues and organs.
- **Muscular Tissue**: Composed mainly of muscle fibers; ground substance is not a significant component here.
- **Neural Tissue**: Composed of nerve cells; ground substance is not present.

5. **Conclude the Correct Answer**:
- Based on the analysis, the only tissue type that contains modified polysaccharides acting as ground substance is **Connective Tissue**.

### Final Answer:
The modified polysaccharides acting as a ground substance are found in **Connective Tissue** (Option B).
