A vacuole is a membrane-bound organelle found in plant and fungal cells, as well as some protists and animal cells. Its primary function is to store nutrients, waste products, and other substances, helping to maintain cellular homeostasis. In plant cells, vacuoles also play a crucial role in maintaining turgor pressure, which keeps the plant rigid and supports its structure. Additionally, vacuoles can be involved in processes such as degradation and recycling of cellular components.
