procentriól

Procentriól is a term that appears to be a misspelling or a non-standard term. Based on phonetic similarity and common biological terminology, it is highly probable that the intended word is "centriole." Centrioles are cylindrical organelles found in most animal cells and some lower plant cells. They are typically found in pairs, oriented perpendicularly to each other, and are enclosed within a matrix of pericentriolar material. Centrioles play a crucial role in cell division, specifically in the formation of the mitotic spindle. During mitosis, the centriole pair duplicates and the two pairs migrate to opposite poles of the cell. Microtubules then emanate from the pericentriolar material surrounding these centrioles to form the spindle fibers that separate the chromosomes. Centrioles are also involved in the formation of cilia and flagella, which are hair-like appendages used for motility or sensory functions in various cell types. Each cilium and flagellum originates from a basal body, which is structurally identical to a centriole. The exact function and origin of centrioles are still areas of active research in cell biology. They are not found in higher plants or fungi.
