Modes of Locomotion in Protists: 5 Modes

The following points highlight the five modes of locomotion in Protists. The modes are: 1. Pseudopodial Locomotion 2. Flagellar Locomotion 3. Ciliary Locomotion 4. Wriggling Locomotion 5. Locomotion by Mucilage Propulsion. Mode # 1. Pseudopodial Locomotion: It is slow creeping type of locomotion which is per­formed with the help of protoplasmic outgrowths called pseudopodia. Pseudopodial locomotion occurs in sarcodines and [...]
