Cytoskeleton provides Mechanical Strength to Cells
Actin filaments: monomers of actin protein polymerize to form long thin fibres called micro filaments. Micro filaments form a band beneath the plasma membrane to provide mechanical strength and structure to the cell.

Cytoskeleton Aids transport within cells.
Microfilaments can attach to vesicles and pull them into the cell.
Movement of vesicles is thought to be controlled by the cytoskeleton.
Microtubule motors: used to move organelles along within the cell- this requires ATP.

Cytoskeleton Enables Cell movement.
Collection of microfilaments and microtubules are continually in the process of assemply and dissassembly resulting in forces that move the cell.
There can also be sliding motions and lengthening and shortening of these structures.
Actin filaments push against each other causing the cell to move.
