What is a microtubule in a cell?

Answer 1

These are produced by centrioles that are located near the nucleus and they help cells divide. These produce the microtubules which make up the cytoskeleton (the thing which gives the cell support and prevents organelles from flying around).

Answer 2

Microtubules inside the cytoplasm comprise a part of the dynamically changing inner network of protein fibers, collectively called the cytoskeleton. The function of the fibers is to basically maintain the shape of the cell, and anchor or move organelles as needed. If the cell has cilia or flagella, these are mostly made up of microtubules, which slide against each other (using the energy from splitting ATP molecules) and propel the cell.

Answer 3

A microtubule is a tubular structure found in the cytoplasm of cells that plays a critical role in cell division, intracellular transport, and maintaining cell shape. It is composed of protein subunits called tubulin and forms a dynamic network within the cell that can rapidly assemble and disassemble as needed.

Answer 4

Microtubules, being part of the cytoskeleton... help a cell maintain its shape.

Answer 5

In a cell there are spindle fibers that help pull apart the chromosomes during meiosis and mitosis. These spindle fibers are made of microtubules.

Answer 6

Microtubules are a component of the cytoskeleton found in eukaryotic cells. Prokaryotic cells do not contain microtubules.

Answer 7

tiny subcomponents of cells
