This document discusses the locomotion of various microorganisms such as amoeba, paramecium, and euglena. It explains that amoeba use pseudopodia, paramecium use cilia, and euglena use flagella to move through their environments. Examples provided are the bacteria Vibrio cholera and Treponema, which can live in extreme habitats and move via air and water currents.

3. Pseudopodias are the locomotary organs of
amoeba.
The extensions of cytoplasm towards the
direction of movement helps in locomotion.

4. Hair like appendages seen on the surface of
body of paramoecium called cilia helps in
locomotion.
The co-ordinated movement of cilia helps in
movement.

5. These are fresh water organisms found in
stagnant water.
Flagellas are the locomotary organs of euglena.

6. Organisms move by whipping these flagella in
fluid medium.

7. They live in extreme habitats such as hot
springs,deserts,snow and deep ocean.

8. Eg:Vibrio cholera

9. Eg:Treponema

10. They move according to the movement of
air and water.
