The large central vacuole of a mature plant cell is bounded by a membrane called the

Explanation

The tonoplast controls what enters and leaves the cell sap, and the vacuole's contents create the osmotic pressure that keeps the cell turgid and so supports the non woody parts of a plant. It also stores sugars, salts, pigments and waste products. The plasmalemma is the plasma membrane at the cell surface, and the cell wall outside it is not a membrane at all.
