Microtubles originate in the Microtubule Organizing Center (MTOC). Or, more specifically, the Centrosome.
they say hii to each other and then they ask themselves do you want to form one microtubule. That is how they are formed.
In eukaryotic cells.
Centrosome
Prophase
Aster.
Microtubules radiate from the cell center.
kinetochore microtubules are located in the centrosomes and produce the microtubules
Centrioles are two short cylinders that are located near the nucleus and are oriented at right angles to each other. Nine triplets of microtubules are arranged in a circular pattern to form the wall of each cylinder.
They are made up of clusters of microtubules. Microtubules are made of the protein tubuliln and are responsible for cell movement and shape. The microtubules are like "conveyor belts" inside the cell.

microtubules. These microtubules are formed from the centrosomes and attach to the chromosomes at their kinetochores. As the microtubules shorten and lengthen, they pull the chromosomes apart, ensuring that each daughter cell receives the correct number of chromosomes.
Prophase its actually in an indistinct phase called prometaphase and they are formed by the kinetochores putting together microtubules, which makes up the microtubules
Microtubules radiate from the cell center.
kinetochore microtubules are located in the centrosomes and produce the microtubules
The Cytoskeleton is a system of microtubules, in a cell.
microtubules
cyto squelettonit is what gives the cell its shape and what maintain organellesit is formed of microfilaments, microtubules and intermediate filaments
It's called a spindle. Here's the definition, according to The American Heritage Dictionary of the English Language:The spindle-shaped achromatic structure, composed of microtubules, along which the chromosomes are distributed in mitosis and meiosis.
microtubules.... might be right
Centrioles are two short cylinders that are located near the nucleus and are oriented at right angles to each other. Nine triplets of microtubules are arranged in a circular pattern to form the wall of each cylinder.
Kinetosomes can be defined as a basal (also called a basal granule or kinetosome) is an organelle formed form a central and a short cylindrical array of microtubules.
