Nutrition in amoeba


NUTRITION IN AMOEBA


  • Amoeba was first discovered by August Johann Rösel von Rosenhof in 1757.
  • Amoeba is a shapeless unicellular (made up of only one cell) organism.
  • Amoeba obtains its nutrition in a heterotrophic mode.

  • Amoeba eats tiny (microscopic) plants and animals as food which floats in water in which it lives.
  • Amoeba feeds on plankton (microscopic organisms that drift on the oceans' currents) and diatoms present in water.
  • It can form arm- like structures called pseudopodia (pseudo:false; podia: feet), extending from any part of its body as it is shapeless.
  • When it senses food in its surroundings it extends its pseudopodia in that direction and moves towards it.
  • Then it engulfs the food with its pseudopodia.
  • When the food enters its body the amoeba forms a food vacuole around it which contains certain enzymes to digest the food.
  • When the food is digested the unwanted waste is released through its body surface.
