Cytoskeleton Fibers•Microtubules–Hollow tube of tubulin proteins. –Attaches to and moves chromosomes during cell division.
Cytoskeleton Fibers•The cytoskeleton functions as a highway system of sorts along which cellular components move.*Except, the cytoskeleton constantly changes its shape.
Centrioles•Assist in microtubule assembly•At opposite poles during mitosis (cell division)
KinesinsMotor Proteins•How do cellular components use the cytoskeleton like highway system?
Cellular Membrane – Extra Cellular Matrix•Useful in cell-cell communication•Cell-Type identity•Self-identity–Immune system
