Cilia and Flagellum

whiplash movement of their cilia
muscular feet is the locomotory organ in mollusks
A valvelike organ that allows it to eject water in a concentrated stream.
A foot can be scientifically described as an organ of locomotion.
Most reptiles smell through their noses like we do, however snakes and some lizards also have a Jacobson's organ on the roof of the mouth. Reptiles gather scent particles on the tongue and flick them into this organ.
the nervous system
Cholera bacteria has got a flagellum at one pole for locomotion.
muscular system
Spirogyra does not have a specialized organ of locomotion like animals do; instead, it exhibits a form of movement through a process known as "water currents" or passive movement. This filamentous green alga floats in water and can be carried by currents, allowing it to spread. Additionally, spirogyra can undergo a form of reproduction called fragmentation, which helps in its propagation rather than active locomotion.
The flagellum is the organelle in euglena that helps in locomotion. It is a tail-like structure that allows the euglena to move through its aquatic environment by beating in a whip-like motion.
