In which layer of anther wall, cells possess dense cytoplasm and generally more than one nucleus?

Options

A. Epidermis
B. Endothecium
C. Middle layer
D. Tapetum

Answer

To answer the question regarding which layer of the anther wall contains cells with dense cytoplasm and generally more than one nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Anther**: The anther is part of the stamen in flowering plants and is composed of several layers. It typically has four layers: epidermis, endothelium, middle layer, and tapetum.

2. **Identify the Layers**:
- **Epidermis**: This is the outermost layer that provides protection.
- **Endothelium**: The layer beneath the epidermis, which also offers some support.
- **Middle Layer**: This layer is situated between the endothelium and the tapetum.
- **Tapetum**: The innermost layer of the anther wall.

3. **Function of Each Layer**:
- The epidermis protects the anther.
- The endothelium and middle layers provide structural support.
- The tapetum is crucial for the development of pollen grains.

4. **Characteristics of the Tapetum**: The tapetum is known for its unique characteristics:
- It has dense cytoplasm.
- It generally contains more than one nucleus.

5. **Conclusion**: Based on the characteristics and functions of the layers, the correct answer to the question is the **tapetum**.

### Final Answer:
The layer of the anther wall where cells possess dense cytoplasm and generally more than one nucleus is the **tapetum**.
