The ion pumps are still working, so the non-nerve side remains negatively charged inside the cell and positively charged outside the cell. If we look at the charges in the electrocyte now, on one face of the cell they are negatively charged outside the cell and positively charged inside. On the opposite face of the cell there is a negative charge inside the cell and a positive charge outside.

Water therefore would flow out of the root, causing the plant to dry up. 35 The highly specialized roots of mangrove plants. Aerial roots allow the plants to draw up oxygen in oxygen-poor waterlogged soils. [F. ] SURVIVING THE ELEMENTS The second problem is that too much salt can be toxic to a plant.
