Sort the characteristics into Seagrasses, Mangroves, or both.
- Started out as land flowering plants that have gradually evolved to live in sea water.
- Reduce effects of hurricanes
- Must be able to grow totally submersed;
- Must be water pollinated.
- Must be securely anchored to withstand wave action and tidal currents
- 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.
- Sheltered shallow water along the coast in sandy and muddy areas below the low tide level.
- Adapted to live in high saline (salty)
- Able to grow in anoxic (low-no oxygen) waters

Sort the characteristics into Seagrasses, Mangroves, or both.
- 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
- Seagrasses (3)
- Mangroves (4)
- Both (2)
