Describe the role of microtubules in intracellular transport.
Understand the Problem
The question is asking for an explanation of how microtubules function in the transport of materials within cells. This includes their structure, mechanism of action, and significance in cellular activities.
Answer
Microtubules provide tracks for organelle and vesicle transport via motor proteins such as kinesin and dynein.
Microtubules serve as tracks for transporting organelles and vesicles within the cell, facilitated by motor proteins like kinesin and dynein.
Answer for screen readers
Microtubules serve as tracks for transporting organelles and vesicles within the cell, facilitated by motor proteins like kinesin and dynein.
More Information
Microtubules are dynamic, hollow tubes made of tubulin proteins found in eukaryotic cells. They not only support intracellular transport but also play roles in cell shape, division, and signaling.
Tips
A common mistake is to confuse microtubules with microfilaments. Both are part of the cytoskeleton but have different functions and structures. Microtubules are larger and involved in transport, while microfilaments are involved in cell movement and contraction.
