The cytoskeleton is a complex network of proteins found in all eukaryotic cells.
It gives shape to the cell, supports internal structures, and helps with the movement of cell organelles.
Major components:
Microtubules – maintain shape and transport organelles.
Actin filaments – cell movement and cycling.
Intermediate filaments – provide mechanical strength.
