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

**Step-by-Step Solution:**

1. **Understanding the Structure of Anther:**
- The anther is part of the stamen in flowering plants and is responsible for producing pollen. It consists of several layers.

2. **Identifying the Layers of the Anther Wall:**
- The anther wall is made up of four layers: the epidermis, the endothecium, the middle layer, and the innermost layer known as the tapetum.

3. **Functions of the Anther Wall Layers:**
- The outer three layers (epidermis, endothecium, and middle layer) primarily serve protective functions and assist in the dehiscence of the anther, which is the release of pollen.

4. **Focusing on the Innermost Layer - Tapetum:**
- The tapetum is the innermost layer of the anther wall. It plays a crucial role in nourishing the developing pollen grains.

5. **Characteristics of Tapetum:**
- The cells of the tapetum are characterized by having dense cytoplasm and typically contain more than one nucleus.

6. **Conclusion:**
- Based on the characteristics described, the layer of the anther wall that possesses dense cytoplasm and generally more than one nucleus is the **tapetum**.

**Final Answer:**
The layer of the anther wall that possesses dense cytoplasm and generally more than one nucleus is the **tapetum**.
