Question

What does the fibril arrangement of flagella in cells mean? What is the fibril arrangement of flagella in eukaryotic cells?

Answer 1

Fibrillar arrangement of a flagella represents the arrangement of the microtubules in the flagella. The fibrillar arrangement of eukaryotic flagella and cilia is 9+2. It means that the microtubules are arranged in a nine fold radial symmetry called the axoneme. They consist of a total of 11 longitudinal fibrils of which 2 are present in the center and 9 on the periphery.
