Tapetum present in the microsporangial wall occurs between

Options

A. Epidermis and endothecium
B. endothecium and middle layers
C. Epidermis and middle layers
D. Middle layers and sporogenous tissue.

Answer

To solve the question regarding the location of the tapetum in the microsporangial wall, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Microsporangium**:
- The microsporangium (anther) wall consists of four layers: epidermis, endothelium, middle layer, and tapetum.

2. **Identify the Layers**:
- The layers from the outermost to innermost are:
- Epidermis
- Endothelium
- Middle layer
- Tapetum

3. **Locate the Tapetum**:
- The tapetum is the innermost layer of the anther wall. It is situated just outside the sporogenous tissue, which is the tissue responsible for producing pollen grains.

4. **Determine the Position of Tapetum**:
- Since the tapetum surrounds the sporogenous tissue completely, it is located between the middle layer and the sporogenous tissue.

5. **Select the Correct Option**:
- Based on the analysis, the tapetum is present between the middle layer and the sporogenous tissue. Therefore, the correct answer is option D: "middle layers and sporogenous tissues".

### Final Answer:
The tapetum present in the microsporangial wall occurs between the middle layer and sporogenous tissues.
