Process and analyse information from secondary sources and use available evidence to discuss processes used by different plants for salt regulation in saline environments


Halophytes are plants adapted to living in salty environments. They are able to tolerate higher levels than other organisms, or have special mechanisms to control their levels of salt.
o In Australia, the chenopod or goosefoot family is a good example. It includes the saltbushes (genus Atriplex) which have special salt secretion glands in their leaves. Chenopods are the dominant species in salt-marsh communities throughout Australia.
o Mangroves grow in conditions of varying salinity as the tide comes and goes, flooding them regularly with saltwater. Some mangroves such as the grey mangrove secrete salt from special glands in their leaves. Others accumulate salt in their leaves and then shed to leaves to dispose of it.
