One of the most important functions of microtubules is as a structural element in the cell by involving many cellular processes, such as mitosis, cytogenesis, and vesicular. As it moves to mitosis, this process will be facilitated by a subgroup of microtubules known as astral microtubules.
In addition, there are several other functions of microtubules that are important to know. The following are the functions of microtubules and their explanations, including the following:
Support Material Transport
The function of microtubules is to support the transport of materials that are the main components of flagella, cilia, and the spindle fibers of the cell during division. Microtubules play an important role in cell division because each chromosome moves to a cleft cleft that is bound by the mitotic spindle created against the microtubules.
Not only that, the function of microtubules is also as a channel for the flow of cytoplasmic material in the cell which is a structural component of cilia and flagella. Therefore, microtubules play an important role in motility and support the movement of chromosomes during cell division.
Determinants of Cell Motion Direction
Microbultus plays an important role in cell movement, especially in mobilizing cell movement by polymerization and depolymerization as well as forming cilia and flagella for locomotion.
One of the movements carried out by cells is the crawling movement. The crawling movement of mammalian cells, such as fibroblasts in connective tissue, depends on their ability to elongate. The results of this elongation will form lamellipodia and attach to the substrate surface.
Cilia and Flagella
The next function of microtubules is as a constituent of cilia and flagella. In eukaryotes, a special arrangement of microtubules is responsible for vibrating cilia and flagella.
There are many unicellular eukaryotic organisms that move in water with the help of cilia and flagella, one of which is animal sperm. Where cilia appear in large numbers on the cell surface.
