In biology, a vacuole is a membrane-bound space found in the cytoplasm of a plant cell.
These are large size compartments that can occupy up to 90% volume of water.
In fully grown plants, vacuoles play a very significant role as they help out in plant growth, storing water, disposing of waste materials, and protecting cells against external barriers.
In sum, vacuoles are generally small in size but important cell organelles that are present in bacteria, fungi, and protozoa.
