In the Eukayotes does cilia evolve multiple times Does flage

In the Eukayotes does cilia evolve multiple times? Does flagella evolve multiple times? did the presence of cell coveringhs and cell covering composition silica, cellulose and CaCO3 evolve multiple times? Explain and provide support

Solution

Thanks for the question

When one of the two flagella is amputated, the other one immediately begins to resorb into the cell, while the replacement for the amputated flagellum begins to regrow. At some point, the two flagella reach the same length, at which time the resorption stops, and both flagella regrow to normal length with rapid kinetics. It is clear that the cell is seeking to maintain two flagella of equal length. This has been demonstrated in several experiements details of which can be found in literature.
