Prasinococcales Guillou et al. .
Marine planktonic green algae. Cells solitary or forming loose colonies. Cells spherical or subspherical, lacking flagella and organic body scales, with a thin cell wall surrounded by a thick ellipsoidal gelatinous capsule, or with a thick, multi-layered cell wall without gelatinous capsule. Cells with a single cup-shaped chloroplast enclosing a mitochondrion, nucleus, and large Golgi body. Chloroplast with a large pyrenoid surrounded by a starch sheath; pyrenoid matrix penetrated by a bifurcate extension of the cytoplasm and the mitochondrion. Cell division by unequal binary fission in which one of the daughter cells retains the parent wall, while the other is released with a newly produced cell wall. Main pigments include chlorophylls a and b, prasinoxanthin, Mg-2,4-divinylphaeoporphyrin a5 monomethylester (MgDVP), uriolide, and micromonol.
