Meaning and Definition
A small cavity within the cytoplasm of a cell, especially in single-celled organisms like protozoa, that contains ingested food particles and digestive enzymes.
In cell biology, a membrane-bound organelle responsible for the intracellular digestion of food, formed by the engulfment of solid material (phagocytosis). It is a transient structure that fuses with lysosomes to break down nutrients before the waste is expelled.

FAQ
Frequently Asked Questions
No. A food vacuole is a temporary, digestive organelle in some single-celled organisms. Plant cell vacuoles are large, permanent structures mainly for storage, structure, and waste management.
Primarily single-celled, phagotrophic organisms like amoebas, paramecia, and some other protozoa. Some cells in multicellular organisms (e.g., white blood cells) perform similar phagocytosis but may use different terminology (phagosome).
It is formed through phagocytosis: the cell membrane engulfs a solid food particle, pinches off, and creates an internal membrane-bound vesicle containing the food.
Once digestion is complete, the useful nutrients diffuse into the cytoplasm, and the remaining waste material is expelled from the cell through exocytosis.
A small cavity within the cytoplasm of a cell, especially in single-celled organisms like protozoa, that contains ingested food particles and digestive enzymes.
Food vacuole is usually academic, scientific, technical (biology/cell biology) in register.
Food vacuole: in British English it is pronounced /fuːd ˈvæk.ju.əʊl/, and in American English it is pronounced /fuːd ˈvæk.ju.oʊl/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Imagine a tiny Pac-Man (a protozoan) eating a dot. The dot becomes a 'food vacuole'—a little food prison (vacuole) inside Pac-Man where the dot is digested.
Conceptual Metaphor
THE CELL IS A FACTORY: The food vacuole is the 'processing chamber' or 'digestive reactor' where raw materials (food) are broken down.
