Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast 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 hemicellulose‚ pectin and in many cases lignin‚ is secreted by
