Marine Plants NOAA
Primary Producers • Prokaryotes (photosynthetic & chemosynthetic) • Domain Bacteria • Domain Archaea • Eukaryotes (photosynthetic) • Kingdom Protista • Unicellular algae (diatoms, dinoflagellates, coccolithophorids) • Multicellular algae (green, brown, red) • Kingdom Plantae • Seagrasses • Salt marsh plants • Mangroves
True Plants • Kingdom Plantae • Angiosperms – flowering plants • Dominant on land, few in the sea • True leaves, stems, roots, vascular system for food/water transport http://atlasveg.ib.usp.br/English/focara.html
Seagrasses • Subtidal shelf • Shallow (need light) • Relatively sheltered, soft-bottom areas (estuaries) • Mostly tropical, subtropical (eelgrass – temperate) NOAA
Seagrasses • Evolved from land plants, reinvaded ocean (totally marine) • Roots, rhizomes stabilize sediment
Seagrasses • Asexual reproduction – rhizomes • Sexual reproduction – flowers, pollen, fruit, seeds http://www.botany.hawaii.edu/seagrass/thal14f.jpg

Salt Marsh Plants • Intertidal, only partly submerged • Relatively sheltered, soft-bottom areas (estuaries) • Are land plants with salt tolerance • Temperate Flax Pond → (north of Stony Brook)
Salt Marsh Plants • NY distribution (yellow) • Also CT coast of LIS, protected bays of NJ shore • aka “tidal wetlands” http://www.dec.ny.gov/images/fish_marine_images/extent.jpg

Salt Marsh Plants Salt meadow cordgrass / Salt marsh hay (Spartina patens) Spike grass (Distichlis) Salt marsh cordgrass / Smooth cordgrass (Spartina alterniflora) Stony Brook Univ. Flax Pond Digital Library USDA Plants Database
Salt Marsh Plants Sea lavender (Limonium) Glasswort (Salicornia) Stony Brook Univ. Flax Pond Digital Library USDA Plants Database
Salt Marsh Plants • Grasses stabilize mud, soil with roots, rhizomes • Tussocks (Spartina cordgrass with ribbed mussels) Stony Brook Univ. Flax Pond Digital Library
Salt Marsh Plants • Protect coastline, prevent erosion • Filter nutrients, pollutants from runoff • Very productive, provide food and homes for many organisms http://news.lternet.edu/sites/news.lternet.edu/files/imagecache/full_image/images/node451img428.jpg
Mangroves • Intertidal, only partly submerged • Relatively sheltered, soft-bottom areas (estuaries) • Are land plants with salt tolerance • Tropical
Mangroves • Roots (underground and aerial), pneumatophores stabilize sediment http://www.botany.hawaii.edu/faculty/webb/BOT311/BOT311-00/Roots/Mangroves/RedMangrovePhoto.jpg
Mangroves • Underwater habitat http://1.bp.blogspot.com/_AiiYtVE9Gvw/TOAf6KPBDjI/AAAAAAAAACE/ZitvTNzpQ24/s1600/Firesponge.jpg http://fl.biology.usgs.gov/ Kate Fuller (Marine Photobank) / UNEP (http://www.grida.no/photolib/detail/young-red-mangrove-tree-in-the-benner-bay-mangrove-marine-sanctuary-virgin-islands_5c52)
