Reproduction by longitudinal fission is habitual and frequent in this species.
In this way we may distinguish, first, vegetative reproduction, the result of discontinuous growth of the tissues and cell-layers of the body as a whole, leading to (I) fission, (2) autotomy, or (3) vegetative budding; secondly, germinal reproduction, the result of the reproductive activity of the archaeocytes or germinal tissue.
In some Syllids this posterior region separates off from the rest, producing a new head; thus a process of fission occurs which has been termed schizogamy.
Sooner or later, however, the scyphistoma produces free medusae by a process of transverse fission termed strobilization.Advertisement
Protohydra is a marine genus characterized by the absence of tentacles, by a great similarity to Hydra in histological structure, and by reproduction by transverse fission.

Nuclear energy is released through a process called nuclear fission.
Several neutrons are also produced which may go on to strike the nuclei of other atoms causing further fission.Advertisement
Homolytic bond fission means the original pair of (Cl-Cl) bonding electrons is split between the two radicals formed.
Heterolytic fission is more common where a chemical bond is already polar.
Breaking bonds can be referred to as bond fission.

The rod-like bodies from the intenor of the tube, which has considerable resemblance to the zoogloea of many Bacteria, are liberated into the interior of the cells of the tubercle and fill it, increasing by a process of branching and fission.
Nuclear energy is the heat produced by the splitting of uranium atoms in a process called fission.
While efforts are made to contain the radiation produced during the fission process, and containment systems are in place to help prevent leaks and contamination, nuclear energy does have its drawbacks.Advertisement
Since uranium is an unstable element, this leaves a great deal of room for error, radiation leaks and risks fission happening too soon, where it cannot be contained.
Once the fission process is achieved, and the reactors have completed their cycle, the waste products leftover from the uranium must be disposed.
The ovicells are modified zooecia, and contain numerous embryos which in the cases so far investigated arise by fission of a primary embryo developed from an egg.
In the Cyclostomata the primary embryo undergoes repeated fission without developing definite organs, and each of the numerous pieces so formed becomes a free larva, which possesses no alimentary canal.

But it was only after Darwin that the cell-theory of Schwann was extended to the embryology of the animal kingdom generally, and that the knowledge of the development of an animal became a knowledge of the way in which the millions of cells of which its body is composed take their origin by fission from a smaller number of cells, and these at last from the single egg-cell.
In the Phylactolaemata, however, a new colony may originate not only from a larva, but also from a peculiar form of bud known as a statoblast, or by the fission of a fully-developed colony.
