Microtubules are cylindrical structures composed of tubulin proteins that form part of the cytoskeleton in eukaryotic cells. They play critical roles in maintaining cell shape, enabling intracellular transport, and facilitating cell division.
congrats on reading the definition of microtubules. now let's actually learn it.
A network of protein fibers in the cytoplasm that provides structural support and facilitates cell movement.
Kinesin: A motor protein that moves along microtubules carrying cellular cargo toward the plus end.
Centrosome: An organelle that serves as a main microtubule organizing center and is crucial for the formation of mitotic spindles during cell division.
