Scenedesmus sp. Meyen, 1829



This is a genus of green algae whose coenobia are a flat plate of ellipsoidal to spindle-shaped cells that are arranged in a single, alternating or double series with their long axis parallel to one another. The number of cells per coenobium is always a multiple of two, usually 4, 8, 16 or 32. The cell walls may be smooth, corrugated, granulate or spicate. Some are with marginal or lateral spines or teeth. The chloroplast in young cells is laminate that has a single pyrenoid. The chloroplast in old cells fill up the entire cavity.
