Updated On: Sep 3, 2025
- Epidermis
- Endothelium
- Middle layer
- Tapetum
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand the structure of microsporangium.
A microsporangium is a part of the plant that contains the microspores. These structures are vital for the formation of pollen grains.
Step 2: Identify the layers.
The microsporangium has several layers, including: - Epidermis: The outermost layer. - Endothelium: A middle layer responsible for nutrient transport. - Middle layer: Provides structural support. - Tapetum: The innermost layer.
Step 3: Focus on the tapetum.
The tapetum is unique because its cells are binucleate (contain two nuclei). These cells are essential for providing nutrients and enzymes to the developing pollen.
Step 4: Conclusion.
Since binucleate cells are found in the tapetum, the correct answer is (D) Tapetum.
Final Answer: The cells of the tapetum layer in the microsporanguim are binucleate.
