Another name for food vacuoles is the digestive vacuole.
It's an organelle found in protists and other basic eukaryotes.
This organelle resembles a lysosome in appearance.
A food vacuole is a closed digestion sac that is enclosed by membranes.
It's found in unicellular protozoans including amoeba, plasmodium, and others.
They function as an intracellular stomach, digesting the food that has been consumed.
Formation of Food Vacuoles In Protists:
When phagosomes and endosomes combine to produce lysosomes, a food vacuole is formed.
Amoebas and other protozoa obtain food by a process known as phagocytosis or pinocytosis.
Phagocytosis is the process by which a cell uses its plasma membrane to swallow a big food particle, resulting in the formation of a phagosome, an intracellular compartment.
In simple words, it can be concluded that the food vacuoles are formed in protists when food particles are swallowed.
