6. Pseudopodia is the locomotory organ in
amoeba. Amoeba is a unicellular
organism. The extensions of cytoplasm
towards the direction of movement are
the pseudopodia.
12. In bacteria locomotory organs like flagella
are seen. In some bacteria locomotion is
effected by the movement of a spiral
shaped body. Some bacteria do not have
specialised organs for locomotion. They
move according to the direction of flow of
water and wind.
