Angiosperms
• Reproduce with flowering & seeds• Few live in the water• Descended from land ancestors• Live at surface• Most conspicuous: sea grasses & mangroves

Sea Grasses
• Superficially similar to seaweeds• Not true grasses• Found off coasts of North America, Atlantic
coast of Europe, Eastern Asia, temperate Australia, South Africa

Sea Grasses
• Form broad gray or green meadows• Support rich communities of heterotrophs• Life cycle is similar to other angiosperms• 45 species known

Sea Grasses
• Eelgrass - Zostera – Most common sea grass– Muddy shallows of calm bays and estuaries of US
Atlantic & Pacific coasts• Turtle grass (Thalassia) & manatee grass
(Syringodium)– Named after animals that once shared their
habitat

Sea Grasses
• Emerald-green surf grass (Phyllospadix) – possibly most beautiful of all– Seasonal flowers & fuzzy fruit– Survive in turbulent, wave-swept intertidal &
subtidal zones of temperate East Asia & western North America

Mangroves
• Tangled masses of trees in low, muddy coasts in tropical & some subtropical areas
• Large, flowering plants• Never completely submerged
![Page 13: Bell Ringer Define angiosperm. Marine Angiosperms](https://reader035.vdocument.in/reader035/viewer/2022062305/5697bf9b1a28abf838c92dd9/html5/thumbnails/13.jpg)
Mangroves
• Thrive in sediment-rich lagoons, bays, & estuaries of the Indo-Pacific, tropical Africa, and the tropical Americas.
• Distribution depends on temperature, currents, & rainfall
![Page 14: Bell Ringer Define angiosperm. Marine Angiosperms](https://reader035.vdocument.in/reader035/viewer/2022062305/5697bf9b1a28abf838c92dd9/html5/thumbnails/14.jpg)
Mangroves
• The sediment must be covered with brackish or salt water for part of the day
• Prop roots required for supports– Mud doesn’t provide support

Mangroves
• Mangroves in south Florida are among the world’s most widespread and consist primarily of red mangroves (Rhizophora)

Mangroves
• Seeds germinate on trees.• If tide is out, the seed will drop into thick mud
& growth will begin• If tide is in, the seed will drop in the water and
be carried off until it finds a new place to grow

Mangroves
• Mature in 20-30 years• Grow to be 26-33 ft tall
