Answers
Answer:
Function: Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
Types: Vacuoles are membrane-bound organelles that are found in both prokaryotes and eukaryotes cells. Vacuoles are of 4 types: Food vacuole, Sap vacuole, Gas vacuole, Contractile vacuole.

Types of vacuoles :
Sap vacuole (store and concentrate mineral salts as well as nutrients) Contractile vacuole (take part in osmoregulation and excretion) Food vacuole (contain digestive enzymes with the help of which nutrients are digested) Air vacuole (help in buoyancy of cells)
