Abstract
P. perforata cells accumulate K and exclude Na over a wide range of salinity. A partial cytoplasmic volume control is noted between 50 and 100% sea water which is probably due to differential swelling of structural polysaccharides. Ca is especially important in maintaining K and Na concentration gradients in diluted sea water. Rain is potentially a more serious threat to survival of the alga in the intertidal zone, due in part to breakdown of ion transport, than is concentration of sea water.This publication has 12 references indexed in Scilit:
