Volvocaceae
Videos
Volvocaceae are a family of unicellular or colonial biflagellate algae, including the typical genus Volvox, and are collectively known as the volvocine algae. The family was named by Ehrenberg in 1834

Schematic representation of the phylogenetic relationships of the volvocine algae and the parallel evolution of the spheroidal colony. Volvocine algae range from the unicellular Chlamydomonas to the multicellular Volvox through various intermediate forms and are used as a model for research into the evolution of multicellularity. The spheroidal colony is thought to have evolved twice independently within this group: once in the Volvocaceae, from
Astrephomene
Videos
Astrephomene is a genus of green algae in the family Goniaceae, order Chlamydomonadales. The genus was first discovered in 1937 by Mary Pocock and later named by Pocock in 1953. The name comes from th

…Volvocaceae inversion first occurred when the Volvocaceae diverged from the closely related Goniaceae (see figure). It also occurred during evolution of Astrephomene. Inversion differs between the two lineages: rotation of daughter protoplasts during successive cell divisions in Astrephomene, and inversion after…

Schematic diagrams of the two mechanisms of spheroidal colony formation in the volvocine algae. In Astrephomene, rotation of daughter protoplasts occurs in conjunction with the movement of basal bodies during successive cell divisions. In Eudorina, protoplast rotation is lacking during successive divisions; a spheroidal colony is formed by means of inversion after successive divisions.
