Abstract
Cell space is defined as the differences between apparent free sucrose spaces of living and killed discs of the red alga, Porphyra perforata. Calculation of cellular ion concentrations, after subtracting amounts of adsorbed Na and Ca, gives values of 400-490 meq/l cell space for K, 45-67 meq/1 for Na, and zero Ca. If Na and K were present as their chlorides, Porphyra cells would be approximately isotonic with sea water.This publication has 2 references indexed in Scilit:
