Which tissue occurs in homogenous layers or in patches below the epidermis in stem of decotyledonous plants?

Answer

To answer the question "Which tissue occurs in homogeneous layers or in patches below the epidermis in the stem of dicotyledonous plants?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Dicot Stem**:
- Begin by understanding the anatomy of the dicot stem. The stem consists of various layers, including the outermost layer known as the epidermis.

2. **Locate the Tissue Below the Epidermis**:
- In the cross-section of a dicot stem, directly beneath the epidermis, there are specific types of tissues.

3. **Recognize the Tissue Type**:
- The tissue that is found in homogeneous layers or in patches just below the epidermis is known as collenchyma.

4. **Describe the Characteristics of Collenchyma**:
- Collenchyma cells are characterized by their thickened corners due to the deposition of hemicellulose, cellulose, and pectin. This structural feature allows them to provide support.

5. **Explain the Function of Collenchyma**:
- The primary functions of collenchyma include providing mechanical support, rigidity, flexibility, and elasticity to the growing stem.

6. **Conclude with the Answer**:
- Therefore, the tissue that occurs in homogeneous layers or in patches below the epidermis in the stem of dicotyledonous plants is **collenchyma**.

### Final Answer:
The tissue that occurs in homogeneous layers or in patches below the epidermis in the stem of dicotyledonous plants is **collenchyma**.
