1. the membrane that surrounds the vacuole in plant cells
Usage: biology

Examples

• The tonoplast regulates the movement of substances into and out of the vacuole.
• Water transport across the tonoplast is crucial for maintaining cell turgor pressure.
• Researchers studied how ions cross the tonoplast in root cells.
• The tonoplast contains specific proteins that control solute transport.
• Damage to the tonoplast can disrupt the plant cell’s water balance.
• Scientists observed changes in tonoplast permeability under drought conditions.
