Explain the locomotion in amoeba and paramecium.
- It is unicellular and does not have a definite shape.
- In order to move, it thrusts out temporary finger-like projections called ‘false-feet’ or pseudopodia in the direction of movement.
- The cellular contents are pushed forward into the pseudopodium.
- Amoeba moves forward because of this flowing motion of the cytoplasm.
- This manner is often referred as amoeboid movement.
- It has a slipper-shaped body with a flexible membrane called
- The pellicle is covered with short hair-like structure called cilia .
- The cilia beat in an organized manner to propel the organism through water.
- During its movement, the organism rotates in a spiral path.
- It moves forward or backward depending on the direction in which the cilia beats.
- It can also crawl using the cilia on its oral side as tiny legs.
