Halophytes may show cell pressure very much higher than atmospheric pressure. Explain how this can happen?

Halophytes are plants that grow in soils having high concentration of salt. Due to the higher concentration of salt, their cell cytoplasm is hypertonic causing water from the surrounding cells or region to enter the cell cytoplasm. So the turgor pressure of the cell is higher. To make sure this pressure doesn't exceed a certain level, they have salt-secreting glands that removes excess of salts and also has vacuoles that store salt.
