This is a 3D latis like structure present in eukariyotic cells it is made up of three types of protenious filament
1. Micro tubules
2. Micro filaments
3. Intermediate filament
Functions,
1. Provide support to cells
2. Maintain the shape of the cell
3. Prevent unnecessary movements inside the cells
4. Important in formation of various structures
5. Important for cytoplasmic streamy
Micro filaments,
These are very fine solid long filaments which are made up of actine protein molecules.
In the structure of micro filaments there are two long chains of actine molecules tightly twisted around each other.
Micro tubules,
Long filaments made up of tubulin proteins.
