Asexual: binary fission from a partitioned parent cell. Sexual: Conjugation to form a hypnozygote. The Closterium peracerosum-strigosum-littorale (C. psl) complex is a unicellular, isogamous charophycean alga cells that is the closest unicellular relative to land plants. These algae are capable of forming two types of dormant diploid zygospores.
Fission in the mitotic phase of cell division of green algae forms autospores. Cells may use different methods to produce different numbers of autospores or multinucleated autospores; for example, the Dictyochloropsis genus of algae can produce between 4 and 16 autospores when they reproduce.
This genetically distinct individual can then proliferate through binary fission. Some argue that this is not true reproduction but actually a form of growth. [ 4 ] Fission is often prompted in the autumn by a decrease in the abundance of food and follows sexual spawning in summer.
