Transcript

  • 1. Marine Flowering Plants Kingdom Plantae
  • 2. Angiosperms • • • • • • • Autotrophs Have flowers used for sexual reproduction Have pollen Have seeds Multicellular eukaryotes Mostly on land-very few in the ocean Evolved from land plants
  • 3. Seaweeds (algae) vs. Flowering Plants Photosynthesis Structure/Support Anchor vs. Water/Nutrient Absorption
  • 4. Three Groups • Seagrasses • Mangroves • Marsh grasses • VERY IMPORTANT habitat for young marine organisms – they all act like nursery grounds for countless species!
  • 5. Seagrasses • Not true grasses • Found in temperate & tropical coastal bays & estuaries • Subtidal = must stay underwater • Prefer shallow, calm, clear waters • Many species • Zostera (eelgrass) is our type on Long Island More about seagrasses: http:// www.flseagrass.org/ecology.php
  • 6. Pictures of seagrass meadows
  • 7. Seagrass Reproduction • Sexually – stringy pollen carried away by currents • Life cycle like land flowering plants • Asexually – using rhizomes under the sediment
  • 8. Mangroves • • • • Woody trees Tropical & Subtropical Intertidal=Not fully submerged Often roots sticking out of the water • Several species – obviously, none on Long Island
  • 9. Picture of a Mangrove Forest
  • 10. Mangrove Reproduction • Reproduce sexually – with flowers • “Pencil seed” germinates while still attached to parent – If it’s low tide: seed sticks in the mud – If it’s high tide: seed is carried away by current
  • 11. Salt marshes • Found in calm, sheltered bays on East and Gulf Coasts of the US • Intertidal • Several species - our common ones are: – Spartina alterniflora – salt marsh cordgrass – Spartina patens – salt marsh hay Virtual field trip through a salt marsh: http://zottoli.wordpress.com/saltmarshes/spartina-alterniflora /
  • 12. Pictures of Salt Marshes
  • 13. Marsh Grass Reproduction • Sexually – flowers like flowering land plants • Asexually - rhizomes
