* Vacuoles: These are large, fluid-filled sacs that are especially prominent in plant cells. They store water, nutrients, waste products, pigments, and other substances. Vacuoles contribute to cell turgor pressure, which helps maintain cell shape and structure.
* Vesicles: These are smaller, membrane-bound sacs that can store and transport various substances within the cell. They play a crucial role in endocytosis (taking substances into the cell) and exocytosis (releasing substances from the cell).
* Lysosomes: While primarily known for their role in digestion, lysosomes also store enzymes and other materials that could potentially damage the cell.
Other organelles with storage functions:
* Golgi apparatus: Processes and packages molecules for storage or secretion, effectively acting as a sorting center for cellular products.
* Endoplasmic reticulum (ER): The ER is involved in the synthesis and storage of lipids, steroids, and other molecules.
It's important to note that the specific functions of these organelles can vary depending on the cell type and its needs.
