Explain the locomotion in amoeba and paramecium

Explain the locomotion in amoeba and paramecium.

moeba -

  • 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.

Paramecium -

  • It has a slipper-shaped body with a flexible membrane called
    pellicle .
  • 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.
