Growth and division of microalgae are indispensable for their survival and spread throughout the environment. Microalgae divide by two mechanisms: binary and multiple fission. Binary fission constitutes division into two daughter cells, as seen in the majority of eukaryotic organisms; it also represents a transition to multiple fission. Multiple fission, typical for some green algae, leads to division into more than two daughter cells (from 4 to 1024), in principle, 2n. Here, we describe the different organizational types of multiple fission cell cycles, with distinct timing of DNA replication, nuclear, and cellular divisions, and discuss how they are regulated at physiological and molecular levels. We show in detail how different growth conditions, particularly changes in light and temperature, will affect not only growth and the accumulation of macromolecules (RNA, protein, starch) but also, through unknown coordination mechanisms, how the cells perform multiple fission cell cycles to generate the number of daughter cells. Finally, we discuss the relationship between two major algal compartments: nucleocytoplasmic and chloroplastic. Growth and division of the two are intricately intertwined and possibly co-regulated by mechanisms that are not fully understood.
