• Nuclear membrane act as a barrier between karyoplasm and protoplasm.
• Tonoplast is that the membrane of the bodily cavity and acts because the barrier between the bodily cavity sap and therefore the matter of the cell. In animal cell cytomembrane act because the barrier between matter and therefore the atmosphere. as a result of animal cell lack the cell membrane.
