CENTRIOLE Meaning and
Definition
-
A centriole is a small, cylindrical organelle found in the cells of animals and lower plants. It is primarily composed of nine microtubule triplets arranged in a barrel-shaped structure. Centrioles play a crucial role in various cellular processes, particularly in cell division and the formation of the cellular cytoskeleton.
Centrioles are typically found in pairs, with each pair oriented at right angles to each other near the nucleus of a cell, residing in a specialized region called the centrosome. During cell division, the centrioles duplicate themselves, and each pair moves to opposite ends of the cell, forming the poles of the mitotic spindle. The mitotic spindle is a crucial structure that helps separate chromosomes during cell division.
Aside from their involvement in cell division, centrioles also play a vital role in organizing and maintaining cell shape and structure. They serve as nucleation sites for microtubules, which are long, protein-based filaments that form the cytoskeleton. These microtubules provide structural support, help in cellular motility, and act as tracks for the intracellular transport of various molecules.
In summary, centrioles are cylindrical organelles composed of microtubule triplets that are involved in cell division, the formation of the cytoskeleton, and the organization of cellular structure.

Common Misspellings for CENTRIOLE
Etymology of CENTRIOLE
The word "centriole" comes from combining two roots: "centro-" and "-ole".
The prefix "centro-" is derived from the Latin word "centrum", meaning "center". This prefix is often used in biological terms to refer to a central structure or location.
The suffix "-ole" is used to indicate something small or diminutive. It is also frequently used in the field of biology to designate a small structure or organ.
So, when combining these roots, "centriole" refers to a small, central structure. In the context of biology, a centriole is a microtubule-based organelle that primarily plays a role in cell division.
