Vacuole Definition

Vacuolum is a shortened version of the word vacuum in Latin.

An intracellular secretion, excretion, storage, and digestion membrane-bound vesicle located in the cytoplasm of a cell. A vacuole is a membrane-bound cytoplasmic vesicle.

A vacuole contains a mixture of inorganic and organic substances. In some cases, ingested solid particles can be found in the vacuole.

Plants and fungi have it in their cells. It’s also been discovered in protists, mammals, and bacteria cells. Vacuoles come in a variety of sizes and shapes.

Vacuoles serve a variety of purposes as well. One of them is intended to function as a cubicle. Water (particularly in plant cells), waste materials, and tiny molecules can all be found in a vacuole.

It’s a necessary step in isolating elements that could harm the cell. In plant cells with big vacuoles, the vacuole maintains an internal hydrostatic pressure inside the cell, assisting plants by providing support for plant structures like leaves and flowers.

In seeds, the vacuole also serves as a storage vesicle. Proteins required for seed germination are stored in this organ.
