Posted on

Amoeba is a unicellular protozoan and the mode of nutrition is holozoic. It is omnivorous in nature i.e, it can take both plants and animals as food source. Amoeba feeds on unicellular plants or animals such as paramoecium. The various steps of nutrition are ingestion, digestion, assimilation and egestion.

Amoeba sends out finger like pseudopodia up on contact with food and engulfs the food by the process called ingestion. This results in the formation of food vacuole.

Food vacuole releases digestive juices, that results in the breakdown of complex food particles into simple molecules by the process digestion.

The digested food diffuses into the cytoplasm by the process called assimilation. The undigested food is thrown out of the body by the food vacuole, this process is called as egestion clip_image002
