Which of the following is not a major structural component of the eukaryotic cell?

• A. Microtubulues
• B. Actin Filaments
• C. Plasmodesmata
• D. Intermediate Filaments

Answer: (C)

Verified step by step guidance

1. Understand the context: Eukaryotic cells have a complex structure with various components that contribute to their function and integrity.
2. Identify the major structural components of eukaryotic cells: These typically include the cytoskeleton elements such as microtubules, actin filaments, and intermediate filaments.
3. Define each component: Microtubules are cylindrical structures that help in cell shape, transport, and division. Actin filaments are thin fibers involved in muscle contraction and cell movement. Intermediate filaments provide mechanical support for the cell.
4. Recognize the odd one out: Plasmodesmata are channels found in plant cells that allow for transport and communication between cells, not a structural component of the cytoskeleton.
5. Conclude by identifying that plasmodesmata, while important for cell communication, are not considered a major structural component of the eukaryotic cell's cytoskeleton.
