Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. These distinctive features include the following: A large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast that maintains the cell's turgor, controls movement of molecules between the cytosol and sap, stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicelluloses, pectin and in many cases lign
