Ion movement through the symplast to the secretory cells of the glands is probably diffusive and cell to cell via plasmodesmata [connecting channels] (Fitzgerald and Allaway 1991). However, when it is found in oxygen-depleted sediments or flooded for extended periods of time, it often develops peg roots. Others excrete salt, in much higher concentration than seawater, through glands on their leaves. Mangroves are shrubs or small trees that are found in coastal areas where ordinary plants cannot survive. As a pioneer species, grey mangrove is very tolerant of extreme saline conditions as it actively resists the uptake of salt at the roots. (discarded of when the levels are too high) - Mangroves can restrict the opening of their stomata. "Some species have suckers on their undersides that help them to climb rocks and mangrove trees"(Laurie, 1972). Then an ion exchanger, the sodium-hydrogen antiporter, uses the energy of the proton gradient to move sodium ions and protons in opposite directions, at the same time. Many insects feed … 1 Answer.
