Answer:
Dynein arms are molecular constructions that operate the vibrating motion of flagella or cilia.
Explanation:
There are two dynein arms that governs the movement of cilia and flagella, one is the outer arm and the other is the inner dynein arm. The outer dynein arm or ODA of Chlamydomonas is consisted of heavy chains that include- HCS, ICS (2)and LCS (11).
The main significance of dynein arms is their capability to convert ATP energy to mechanical energy. The ODA arms can identify the fluctuation of calcium concentration which has an important role in waveform alteration of cilia and the frequency of beat in flagella.
