mangrove salt regulation? (1 Viewer)

[brose]

hey i hav sum Q's on mangroves and wood LOVE some help!!
question is : what r the "Structures used for salt regulation" and "Processes used for salt regulation" for the mangroves species of: the Narrow leafed wilsonia, beaded samphire and sea blight.
ANY help wood b much appreciated!!

Coping with salt

• The first line of defence for many mangroves is to prevent much of the salt from entering by filtering it out at root level. Some species can exclude more than 90 percent of salt in seawaters (Rhizophora, Ceriops, Bruguiera and Osbornia species are all ‘salt-excluders’.)
• Another method is to quickly excrete salt which has entered the system. The leaves of many mangroves have special salt glands which are among the most active salt-secreting systems known. It is quite possible to see and/or taste the salt on the leaf surfaces of species which choose this method. (Examples of ‘salt-secretors’ include Avicennia, Sonneratia and Acanthus.)
• A third method of coping with salt is to concentrate it in bark or in older leaves which carry it with them when they drop. (Lumnitzera, Avicennia, Ceriops and Sonneratia species all use this.)

ohh yeah i remember this... they can store salt in their leaves them drop them off... theres a word 4 it but i dont remember it LOL

This is how i remembered it - SEA (suitable as their in esturies lol)

Secretion - They have glands on their leaves which release salt, that can be blown and washed off

Exclusion - They have structures in their roots which prevent the uptake of salt in water

Accumulation - They sacrifice certain branches by pumping salt to that area, and letting it die, to protect the rest of the plant

Accumulation?

Grey Mangroves:
- Salt Exclusion: Special glands in the mangroves can actively exclude the salt from the water, so that the water absorbed has a lower salt concentration than the water in the environment.
- Salt Accumulation: Salt is accumulated in old leaves that drop off, so that the salt is out of the plant’s system
- Salt Excretion: Salt can be excreted from the underside of the leaves of the mangrove plants; salt crystals form under the leaves.
