Total questions: 14
Worksheet time: 7mins
Both types of marine plants (submergent & emergent)
have stipes & holdfasts
provide habitats & produce oxygen
have waxy coverings & live in meadows
live at the shore & expel salt
These are bioluminescent dinoflagellates
Symbiodinium
HAB's
Sargassum
Noctiluca
These measure about 20 – 80 microns in size
Dinoflagellates
HAB's
Symbiodinium
Diatoms
Which one lives inside coral polyps?
Diatoms
Symbiodinium
Noctiluca
red algae
These measure about 30 – 150 microns in size
Diatoms
Sargassum
brown algae
Dinoflagellates
Biologists believe these gave rise to land plants
diatoms
green algae
mangroves
kelp
Cell walls of cellulose & the presence of chlorophyll a & b mean
mangrove leaves have a waxy covering
red algae can live deeper than any other algae
land plants may have evolved from green algae
seagrasses can withstand high salinity
How a marine plant resists dehydration
waxy leaf coverings
holdfasts
cell walls made of cellulose
produce excess oxygen
Holdfasts, stipes, blades & pneumatocysts are found
on red algae
on mangroves
on Sargassum
on kelp
