Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of plant cell structures and intercellular connections.
Step 2: Detailed Explanation:
Desmotubules are tubular structures found within plasmodesmata.
Plasmodesmata are channels that connect adjacent plant cells.
Desmotubules are derived from the endoplasmic reticulum (ER) and connect the ER of adjacent cells.
Golgi bodies (A): Involved in protein processing.
Endoplasmic reticulum (B): While desmotubules are derived from ER, they are specifically found in plasmodesmata.
Cytoskeleton (C): Provides structural support.
Thus, desmotubules are identified in plasmodesmata.
Step 3: Final Answer:
Thus, desmotubules are identified in plasmodesmata, which corresponds to option (D).
