A vacuole (/ ˈvækjuːoʊl /) is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. [1][2] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution, though in certain cases they may contain sol...

Jul 19, 2018 · A vacuole is an organelle in cells which functions to hold various solutions or materials. This includes solutions that have been created and are being stored or excreted, and those that have been phagocytized, or engulfed, by the cell.

Sep 21, 2021 · What is a vacuole - its facts, meaning, & purpose. Learn what it looks like, & where it is located. Also, what it does in a cell, described with its main role, examples, & picture

Mar 8, 2025 · Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs, performing functions such as storage, ingestion, digestion, excretion, and expulsion of …

Sep 30, 2022 · A vacuole is a membrane-bound structure in the cytoplasm of a cell that’s primarily involved in various biological processes, such as intracellular secretion, excretion, storage, and digestion. It is surrounded by a single membrane and contains various substances.

Mar 14, 2025 · The tonoplast contains proton pumps that actively transport H+ ions into the vacuole, creating an acidic environment. This pH regulation is vital for enzyme activity, nutrient storage, and overall cellular metabolism. In fungi, vacuoles also play a key role in maintaining cytosolic pH, which is essential for survival in diverse environments. 4.

6 days ago · A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
