Tetraselmis cordiformis



caption Tetraselmis (syn: Carteria) cordiformis (Chlorophyta, prasinophyceae) is a relatively large single cell ellipsoidal-ovoidal species identified by its 4 equal-length flagella arising from an anterior depression of the cell body. The chloroplast is cup-shaped with a pyrenoid at the bottom; a single large stigma; two contractile vacuoles at the base of flagella. In Lake Kinneret it occurs frequently but usually in low abundance, except one occasion in 1997 in which for a few days the lake water turned bright green due to a bloom of this species, this bloom disappeared within a few days and was missed by our routine sampling program
