Which statement is correct regarding the bending movements of cilia and flagella?
A) They are accomplished by alternate solation and gelation of the cytosol.
B) They involve the alternate assembly and disassembly of actin filaments.

Question

Quizplus · Accepted Answer

Bending movements of cilia and flagella are due to the sliding of adjacent microtubule doublets past one another. This sliding is powered by the activity of dynein, a motor protein. This movement generates a bending force that causes the cilia or flagella to bend and thus propel the cell.
