In one form, they contain a substance called cell sap.
In Plasmodium, proteases (PRO-tee-aze-iz) are found in the "food" type of these organelles. In one form, they contain a substance called cell sap. In plants, proteins called aquaporins (ock-wuh-PORE-inz) are found in the membrane surrounding this organelle, called the (*) tonoplast (TOE-noh-plast). This organelle can take up as much as ninety percent of a plant cell. This organelle maintains the plant's rigidity by causing a pressure called turgidity that is determined by its water content. For 10 points, name these storage organelles found in many cells.
