They are capable of degrading the cell wall of their prey to feed exclusively on the protoplast material (as seen in certain green algae; see image). [4] They are not bacterivorous. They propagate by binary fission. No plasmodia have been observed. They inhabit freshwater-fed ecosystems. [1]
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.
Binary fission is generally rapid, though its speed varies between species. For E. coli, cells typically divide about every 20 minutes at 37 °C. [11] Because the new cells will, in turn, undergo binary fission on their own, the time binary fission requires is also the time the bacterial culture requires to double in the number of cells it ...
The behaviors of digestion and reproduction through binary fission in the free-living state are very common, but they are also capable of invading certain algae to digest and reproduce. [ 1 ] [ 2 ] In particular, Orciraptor agilis has a gliding velocity averaging 12 μm per second, and a flapping frequency of the anterior flagellum of 1.4–2.3 ...
The cause of the blooms is still poorly understood. [ 8 ] When a large bloom occurs, resources become limited, and this means greater competition for space and sunlight between several marine organisms—as the genus Karenia start dying they release their neurotoxins , which can kill fish and other organisms.

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.
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.
Amitosis, also known as karyostenosis, direct cell division, or binary fission, is a form of asexual cell division primarily observed in bacteria and other prokaryotes. This process is distinct from other cell division mechanisms such as mitosis and meiosis , mainly because it bypasses the complexities associated with the mitotic apparatus ...
