The cytoskeleton is the internal structure that maintains the shape of the cell and is made up of proteins that polymerize into filamentous structures.
What are proteins?
They are biomolecules made up of structural units called amino acids.
The cytoskeleton is a protein-based system found in cells that provides internal support and is constructed of three main types of filaments (proteins), these are microtubules, microfilaments, and intermediate filaments.
Therefore, we can conclude that the cytoskeleton is the internal structure that maintains the shape of the cell and is made up of proteins that polymerize into filamentous structures.
