ATpases and Membrane Properties in Relation to Ecological Differences
Animal cells are surrounded by comparatively well regulated body fluids. In contrast, plant cells - and particularly the root cells - must actively be able to maintain their cytoplasm and organelles in a state that is sufficiently constant to allow the biochemical processes to proceed within the limits of life, and this in spite of the often quite considerable short- time fluctuations that occur in water and ion status and in temperature of the surrounding soil and air. The regulation of ion transport through the plasmalemma should thus have a key role for the internal balance of the plant cell.
