Which cytoskeletal component is primarily involved in transport and mitosis?

Understand the Problem

The question is asking about the specific cytoskeletal component that plays a major role in cellular transport and mitosis, which defines its functional significance within the cytoskeleton.

More Information

Microtubules are cylindrical structures made of tubulin proteins. They are dynamic structures that constantly change in length by polymerizing and depolymerizing. They are essential for maintaining cell shape, enabling intracellular transport, and separating chromosomes during mitosis.

Tips

A common mistake is confusing microtubules with microfilaments or intermediate filaments, which have different primary functions.
