The microtubule-organizing center is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the orga

Microtubules are biopolymers of tubulin that form part of the cytoskeleton to provide structure and shape to a eukaryotic cell. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm an
Components of the eukaryotic cytoskeleton include: nuclei (blue), microtubules (green), and actin filaments (red).

Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.
