Question

What would happen if a cell did not have a cytoskeleton?

Answer 1

The cytoskeleton is a complex network of protein filaments that are linked together. The cytoskeleton is present in the cytoplasm of cells.

Complete answer:
The cytoskeleton performs a large amount of functions. The cytoskeleton provides rigidity to a cell and gives the cell its shape and structure. The cytoskeleton provides mechanical resistance from deformation to a cell. The cytoskeleton stabilizes tissues through contact with extracellular connective tissue. The cytoskeleton also contracts and deforms the cell along with the cellular environment. This allows the migration of cells. The cytoskeleton is involved in cell signalling pathways, in the uptake of extracellular substances and in the segregation of chromosomes during cell division. The cytokinesis phase in cell division is used as a base to arrange the contents of the cell in the cytoplasm.
The absence of a cytoskeleton in a cell would lead to a lack of structural integrity in the cell. The cell would lose its shape and structure and would be permanently deformed. The cell would have no mechanical resistance from external pressure and would be easily damaged.

Note:
The cytoskeleton extends from the nucleus of the cell to the cell membrane. It is composed of the same proteins throughout the various cells. The cytoskeleton is composed of three main components in a eukaryotic cell. They are:
- Microfilaments
- Intermediate Filaments
- Microtubules
These components of the cytoskeleton grow or disassemble rapidly based on the requirements of the cell.
