Characteristics
– Phloem(carries
nutrients) and xylem
(support)
– Root stem and leaf
structures
– Seed and fruit
– Halophytic – salt
tolerant

Hydrophytes – Live beneath the water
Can flower and germinate while submerged
Vegetative growth with horizontal rhizomes
Primary producers
Stabilize sediments
Provide habitat
Slow currents and wave action
Cover less floor than seaweeds, so more
habitat
Salt marsh

Must be exposed to air by ebbing tide to live
Located in the intertidal zone
Facultative halophytes – can tolerate salty
water as well as fresh water conditions
Adaptations – thick cuticle, salt glands
Serve as nurseries, feeding ground
Accumulates and stabilizes sediments
Mangroves

Red Mangrove – closest to water
– Prop roots and drop roots
– Propagule – seedling
– Salt excluder

Black mangrove
– Pneumatophores(airhole) – stick up out of water
and aid in root aeration and gas exchange
– Slat excreter

White Mangrove - farthest from water
– No visible arial root
– Leaves taste list salt
