Explanation:
Detailed explanation-1: -The tonoplast is the cytoplasmic membrane surrounding a vacuole, separating the vacuolar contents from the cell’s cytoplasm.
Detailed explanation-2: -tonoplast. The tonoplast is the cytoplasmic membrane surrounding a vacuole, separating the contents of the vacuole from the cell’s cytoplasm.
Detailed explanation-3: -The ‘vacuolar membrane’ is also known as Tonoplast. So, the correct answer is, ‘Membrane boundary of the vacuole of plant cells’.
Detailed explanation-4: -Tonoplast is the membrane of plant cell vacuole. As the plasma membrane it is selectively permeable for solute particles and allows selected solute particles to cross through, it surrounds the cell sap.
