Volvox carteri, a colonial green algae, features a unique life cycle with sexual and asexual phases, forming small colonies of somatic and reproductive cells. It serves as a crucial model organism in the study of multicellularity and complexity evolution due to its differentiation ability and genome size, comprising 14,520 protein-coding genes with a high intron percentage. With 55.3% GC content, it offers valuable insights into the evolution of multicellular life.
