vacuole

A vacuole is a membrane-bound compartment found in cells, mainly in plant and fungal cells. It acts as a storage unit, holding substances like water, nutrients, waste products, and enzymes. In plants, the vacuole can occupy a large part of the cell and helps maintain turgor pressure, which keeps the plant firm and upright. It also plays a role in waste disposal, buffering pH, and storing important compounds. Think of it as a flexible storage tank within the cell, essential for maintaining cell stability, health, and function.
