PHAGOCYTOSIS

  • Nutrition in an Amoeba occurs through a process called phagocytosis.
  • Phagocytosis is the process by which the food is engulfed by the organism.
  • The mode of nutrition in amoeba is known as holozoic nutrition.
  • It involves the ingestion, digestion and egestion of food material.

Process Of Nutrition In Amoeba�

  • The different processes involved in holozoic nutrition in amoeba are:

  • Ingestion is the process of taking in the food into the body either by swallowing or absorbing it.

  • Digestion is the process of breaking the insoluble and large food molecules into soluble and minute molecules

  • Absorption the nutrients from the digested food material are absorbed into the cell’s cytoplasm by leaving behind the undigested particles. This process is called diffusion.

  • Assimilation is the process of obtaining energy from the absorbed food molecules

  • Egestion is the process of excretion of undigested food material
