Overview of the Cytoskeleton
Multiple Choice
In the context of the cytoskeleton, which cellular structure primarily helps a cell maintain its shape and provides mechanical support?
A
The nucleolus
B
Ribosomes
C
Lysosomes
D
The cytoskeleton (network of microtubules, actin filaments, and intermediate filaments)
Verified step by step guidance1
Understand that the cytoskeleton is a complex network of protein fibers within the cell that provides structural support and helps maintain the cell's shape.
Recognize the main components of the cytoskeleton: microtubules, actin filaments (microfilaments), and intermediate filaments, each contributing to mechanical strength and shape maintenance.
Identify that other cellular structures like the nucleolus, ribosomes, and lysosomes have different functions: the nucleolus is involved in ribosome production, ribosomes synthesize proteins, and lysosomes digest cellular waste.
Conclude that among the options given, the cytoskeleton is the primary structure responsible for maintaining cell shape and providing mechanical support.
Summarize that the cytoskeleton's dynamic and interconnected network allows the cell to resist deformation and maintain its integrity under various conditions.
