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.
Paramecia reproduce asexually, by binary fission. During reproduction, the macronucleus splits by a type of amitosis, and the micronuclei undergo mitosis. The cell then divides transversally, and each new cell obtains a copy of the micronucleus and the macronucleus. [10] Fission may occur as part of the normal vegetative cell cycle.
The thick algae on Lake Okeechobee has caused a State of Emergency, keeping the water behind the flood gates and stopping the spread down the rivers and eventually the coast. Algae causes State of ...
Reproduction among these organisms is asexual by binary fission, during which the diatom divides into two parts, producing two "new" diatoms with identical genes. Each new organism receives one of the two frustules – one larger, the other smaller – possessed by the parent, which is now called the epitheca ; and is used to construct a second ...

Dinophysis thecae are divided into halves by a sagittal fission suture. [4] There are five types of thecae ornamentation in this genus, [4] and those are a useful character for species identification. [4] Dinophysis mainly divide by binary fission. [4] Dinophysis chloroplasts are usually rod-shaped or granular and yellow or brown colored. [4]
Euglena reproduce asexually through binary fission, a form of cell division. Reproduction begins with the mitosis of the cell nucleus , followed by the division of the cell itself. Euglena divide longitudinally, beginning at the front end of the cell, with the duplication of flagellar processes, gullet and stigma.
