green alga
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as ...

[Adarme-Vegas, T.C., S.R. Thomas-Hall, D.K.Y. Lim, and P.M. Schenk, 2014.Marine Drugs 12(6): 3381-3398] state that a reduction in biomass of Tetraselmis spp. was observed in high salinity cultures (50 ppt) as well as in near-freshwater salinity cultures (5 and 10 ppt). Changes in salinity primarily altered biomass productivity with cultures in 30 and 40 ppt having the highest growth rate and final productivity. Salinity had no effect on the percentage of EPA or total Fatty Acid production.
