Zoospores are mobile spores that use flagella for their control. Various species of protists, bacteria and fungi use them as a means of propagation. Flagella can be of two types. Stramopyle flagella (Stromopiles) containing lateral filaments called mastigonum. These are located perpendicular to the main axis of the flagellum. The whip-like flagella lack mastigonum. The number and distribution of flagella …
