The storage compartment in a cell is commonly referred to as a vacuole.
Vacuoles are membrane-bound structures within the cytoplasm of a cell. They can hold various substances, such as nutrients, waste products, or even water, depending on the cell’s needs. In plant cells, vacuoles are often very large and serve as storage spaces as well as helping to maintain turgor pressure, which keeps the plant rigid and upright. In contrast, animal cells may have smaller vacuoles that are more involved in storage and transport processes.
