One function of microtubules is being conveyor belts inside of Cells. They move vesicles, granules, organelles and chromosomes via special attachment proteins. See MTOC - micro-tubule organizing centers.
They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein. These linear polymers are called protofilaments. The tubulin molecules are bead like structures. They form heterodimers of alpha and beta tubulin. A protofilament is a linear row of tubulin dimers.
What else can I help you with?
The hollow tubes of protein that help maintain the shape of the cell is what?
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
What happens to the nonkinetochore microtubules during telophase?
During telophase, nonkinetochore microtubules depolymerize and disappear as the cell prepares to complete the process of cell division. These microtubules are no longer needed once the chromosomes have reached opposite poles of the cell.
What protein forms microtubules in the cell?
tubulin
What cytoskeletal element are most stable?
Microtubules are considered the most stable cytoskeletal element in the cell. They are composed of tubulin subunits and provide structural support and stability for the cell. Microtubules are involved in various cellular processes, including cell division and intracellular transport.
What cytoskeletal element give the cell shape?
The microtubules give the cell its shape.
What produces microtubules during cell division in animals?
The centrosome, which contains a pair of centrioles, functions as the primary microtubule-organizing center during cell division in animals. The centrioles help nucleate and organize the formation of microtubules that make up the spindle apparatus, which is essential for segregating chromosomes during cell division.
What is the stystem of microtubules?
The Cytoskeleton is a system of microtubules, in a cell.
The hollow tubes of protein that help maintain the shape of the cell is what?
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
What microtubules are necessary for sorting the chromosomes in cell division?
The kinetochore microtubules
Which cytoskeletal element radiates from the cell center?
Microtubules radiate from the microtubule-organizing center (MTOC) located near the center of the cell. They play a key role in various cellular processes, including cell division and intracellular transport.
What is the function of the centrosomes?
it is an area in the cell where microtubules are produced.

How are centrioles involved in the formation and organization of microtubules within the cell?
Centrioles are involved in the formation and organization of microtubules within the cell by serving as the main organizing centers for the assembly of microtubules. They help to nucleate and anchor the microtubules, which are essential for various cellular processes such as cell division and intracellular transport.
What part of cell is made up of microtubules and helps organize microtubules involved in cell division cilia and flagella?
The centrosome is the part of the cell that is made up of microtubules and helps organize microtubules involved in cell division, cilia, and flagella. It contains a pair of centrioles that serve as the main microtubule organizing center in animal cells.
Are microtubules in plants or animals?
They are found in BOTH PLANT AND ANIMAL CELLS because they play a major role to keep the whole cell in function!
What happens to the nonkinetochore microtubules during telophase?
During telophase, nonkinetochore microtubules depolymerize and disappear as the cell prepares to complete the process of cell division. These microtubules are no longer needed once the chromosomes have reached opposite poles of the cell.
