Question

Name the system that controls the fastest swimming movement of protozoans and writes its components.

Answer 1

The fastest swimming movements in protozoan are due to 2 major structures:  

i. Flagellar propulsion: The eukaryotic flagellum is a membrane-bound, whiplike structure found in protozoan. The structure of the eukaryotic flagellum consists of a pair of central microtubules surrounded by a circle of nine pairs of microtubules. undulation from the tip to the base causes pulling force and causes the organism to pull forward fastly.

ii. Ciliary movements: Ciliates have an increased number of beating flagella on the cell surface, thereby enabling greater power and speeds to be developed against viscous forces.
