Sort the characteristics into Seagrasses, Mangroves, or both.

Able to grow in anoxic (low-no oxygen) waters
Roots and leaves totally submersed
Adapted to live in high saline (salty)
Must be securely anchored to withstand wave action and tidal currents
Must be able to grow totally submersed;
Must be water pollinated.
Started out as land flowering plants that have gradually evolved to live in sea water.
Leaves sweat out salt or have a waxy waterproof covering
Sheltered, shallow, nutrient-rich water along the coast in sandy and muddy areas at the tidal level.
Reduce effects of hurricanes
Sheltered shallow water along the coast in sandy and muddy areas below the low tide level.

Reproduce Sexually –produce a flower that blooms underwater and is pollinated underwater by pollen carried in water currents.
Reproduce Asexually – rhizomes -horizontal stems sending out roots and shoots that occur below the sediments
Harmed by overfishing and Dredging
Reproduce Sexually – produce flowers that are pollinated. Seeds germinate while still on the plant - roots are on top. Seed falls and floats until it roots.
Have Pneumatophores/erect/aerial roots that form of upward appendages that are not submerged underwater so the root can get oxygen in a low oxygen environment.
Have Lenticels/ small pores present on aerial roots – allows for gas exchange. They can be blocked by crude oil, pollution, and attacks by parasites.
Harmed by deforestation for wood/timber
Part of food chains & webs
Nursery areas
