Vedclass · Answer

(B) Halophytes grow in saline environments where the water potential of the soil is very low. To absorb water from such hypertonic soil,these plants accumulate high concentrations of inorganic ions and organic solutes within their vacuoles. This accumulation significantly lowers the osmotic potential of the cell sap,allowing water to enter the cells via osmosis. As water enters,it exerts a high turgor pressure (cell pressure) against the cell wall,which is essential for maintaining the structural integrity and metabolic activity of the plant in saline conditions. While salt glands help in removing excess salt,the high internal cell pressure is primarily a result of the high solute concentration maintained to facilitate water uptake.

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