Microtubules

Definition

Microtubules are small, tube-like structures within cells that help maintain their shape and play a critical role in various cellular processes, including cell division and the transport of materials inside cells.

Scientific / Technical Definition

Microtubules are cylindrical polymers of tubulin that are part of the cytoskeleton in eukaryotic cells. They provide structural support, facilitate intracellular transport, and are crucial in the process of mitosis as they form the mitotic spindle, which separates chromosomes during cell division.

Benefits

• Essential for cellular division, which is critical for growth and repair.
• Enable intracellular transport vital for cellular function.
• Contribute to maintaining proper cell architecture.

Examples

• Microtubules are not found in food but are present in human cells and all eukaryotic organisms.

Additional Information

• Importance: Microtubules are crucial for muscle cell growth and repair as they facilitate the organization and distribution of proteins needed for muscle contraction.
