Question
What are the functions of the cytoskeleton?
- To provide mechanical support
- To give shape to the cell
- Hold different cell organelles
- All of these
Hint:
The cytoskeleton is present inside the cytoplasm to ensure proper structure.
The correct answer is: All of these
- The cytoskeleton performs all the given functions which include providing mechanical support, ensuring the shape of the cell, and holding different organelles in the right place.
- The cytoskeleton refers to proteinaceous fibers which are responsible for providing a proper framework to the cell. They include all material inside the cytoplasm except the nucleus.
- The main function of the cytoskeleton is to provide shape and structure to the cell. It gives mechanical support to prevent the cell from collapsing. It also organizes the organelles in the right place.
There are three types of the cytoskeleton. They are microtubules, microfilaments, and intermediate filaments.
