Tetraselmis suecica is a marine green alga.[2]
Tetraselmis suecica consists of unicellular, motile cells with four equal flagella about as long as the length of the cell, arising from a single apical furrow. The cell wall is smooth and rigid. Cells are 9–11 μm long, 7-8 μm wide, and 4.5–6 μm thick. Cells are compressed, ovoid in dorsal view and ellipsoid in lateral view. Cells contain a single, campanulate chloroplast which is dissected into two or four lobes. The chloroplast has a conspicuous basal pyrenoid surrounded by a starch sheath. The stigma is small, reddish and situated at the base of the cell near the pyrenoid. Cells contain a single central nucleus, several pale spherical bodies in the chloroplast, and several dense bodies in the apical lobes.[3]
Reproduction occurs by division of the protoplast within the cell wall, resulting in daughter cells which have flagella prior to release. Cysts are sometimes formed within culture.[3]
