The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell. Small nonpolar molecules can easily across the phospholipid bilayer of plasma membrane because it is hydrophobic. Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.
Halophiles are extremophiles that thrive in environments with very high concentrations of salt. <span>Halophiles prevent this loss of water by increasing the internal osmolarity of the cell by accumulating </span>osmoprotectants<span> or by the selective uptake of potassium ions. Hope this helps.</span>
