. The classification of lower organisms. Biology. 64] The Classification of Lower Organisms Organisms producing motile cells with paired unequal flagella which Vlk (1931) found to be respectively pantoneme and acroneme, differing from Ochromonadalea in being of a green or yellow-green color, and in being mostly of algal body type, i. e., walled and non-motile. The cell wall consists usually of two parts which become separate when the cell divides; the two parts are believed to be distantly homologous with the wall and pRig of the statospores of Ochromonadalea and Silicoflagellata (Pascher, 193
