To produce spores.

In the vascular cryptogams and phanerogams it takes place in the spore mother cells and the reduced number is found in all the cells of the gametophyte, the full number in those of the sporophyte.

Under proper conditions, the spore may revert to the actively multiplying form of the bacteria.

Equipment should be single use only or sterilized in a recently spore tested autoclave sterilizer.

Sometimes the two cavities are restricted to the two ends of the spore, the polaribilocular type and the two loculi may be united From Beitrcge zur Wissenschaftlichen Botanik.

Delage has distinguished as multiplication those cases in which the new individual arises from a mass of cells which remain a part of the maternal tissues during differentiation, reserving the term reproduction for those cases in which the spore or cell which is the starting-point of the new individual begins by separating from the maternal tissues; but the distinction is inconvenient in practice and does not appear to carry with it any fundamental biological significance.

No agreement has ever been arrived at regarding the consistent use of the term spore.

According to the characters of the last, we might theoretically divide them into conidiophores, sporangiophores, gametophores, oidiophores, &c.; but since the two latter rarely occur, and more than one kind of spore or spore-case may occur on a sporophore, it is impossible to carry such a scheme fully into practice.

Gelatinous or mucilaginous degenerations of cell-walls are frequently employed in the interests of spore dispersal.

The mucilage surrounding endospores of Mucor, conidia of Empusa, &c., serves to gum the spore to animals.

Life-history in some cases very complex and with well-marked sexual process and alternation of generations, in others much reduced; basidium (promycelium) derived usually from a thick-walled spore (teleutospore).

They are characterized especially by the zygospores, but the asexual organs (sporangia) exhibit interesting series of changes, beginning with the typical sporangium of Mucor containing numerous endospores, passing to cases where, as in Thamnidium, these are accompanied with more numerous small sporangia (sporangioles) containing few spores, and thence to Chaetocladium and Piptocephalis, where the sporangioles form but one spore and fall and germinate as a whole; that is to say, the monosporous sporangium has become a conidium, and Brefeld regarded these and similar series of changes as explaining the relation of ascus to conidium in higher fungi.

According to his view, the ascus is in effect the sporangium with several spores, the conidium the sporangiole with but one spore, and that not loose but fused with the sporangiole wall.

In the first group zygospores can arise by the union of branches from the same mycelium and so can be produced by the growth from a single spore; this group includes Spordinia grandis, Spinellus fusiger, some species of Mucor, &c. The majority of forms, however, fall into the heterothallic group, in which the association of branches from two mycelia different in I nature is necessary for the 2, formation of zygospores.

These structures cannot 3, then be produced from the product of a single spore nor even from the thalli derived from any two spores.

Miss Nichols fi -ids that it occurs very soon after the germination of the spore in Cc sinus, but no fusion of cells or migration of nuclei was to be observed.

It will be remembered that in M usci, the asexual spore somewhat similarly gives rise to a protonema, from which the adult plant is produced as a lateral bud.

The reduction stage, on the other hand, is the first division of the mother-cell of the spore.

While starch occurs commonly as a cell-content in the majority of the Green Algae no trace of it occurs in Vaucheria and some of been distinguished, relatively few have been traced from spore to spore, as the flowering plants have been observed from seed to seed.

Schizomycetes such as Clostridium, Plectridium, &c., where the sporiferous cells enlarge, bear out the same argument, and we must not forget that there are extremely minute " yeasts," easily mistaken for Micrococci, and that yeasts occasionally form only one spore in the cell.

A motile rodlet with one cilium and with a spore formed inside.

Spore - formation in O Vibrio- like (c) and o' I O Spirillum-like (a, b, d) o Schizomycetes.

An arthrospore, however, is not a true spore but merely an ordinary vegetative cell which separates and passes into a condition of rest, and such may occur in forms which form endospores, e.g.

The spore may be formed in short or long segments, the cellwall of which may undergo change of form to accommodate itself to the contents.

As a rule only one spore is formed in a cell, and the process usually takes place in a bacillar segment.

The outermost layer of the cell-wall of the ripe spore splits along spiral lines, giving rise to the elaters; these two long strips of wall, attached by their middle points to the spore, tend to straighten out in dry, and close round the spore in damp air.

The development of the microand megasporangia is the same up to the stage of isolation of the spore mother-cells.

The megaspore becomes filled with the female prothallus, the formation of cell-walls commencing at the pointed end of the spore, where from the first the nuclei are more numerous, and later extending to the base.

The prothallus developed from the spore is green and in most cases dorsiventral, bearing the archegonia and antheridia on the under surface.

A consideration of the biology of the sorus gives an insight into the advantages obtained by the one type over the preceding, as regards protection, spore production and the dispersal of the spores, and thus indicates the way in which natural selection may have acted.

The spore or embryo-sac. roots, or at least their functional repre sentatives, resembled those of Lepidodendron.

In C, lying horizontally, an additional cell has been cut off between rhizoid and spore.

Some rely on insects for spore dispersal, whilst others use people or animals to ensure their spread.

Both types are a simple pinnate form but the pinnae of the spore producing fronds are very much narrower.

The method used was to make spore suspensions and lawns of the fungus on agar plates.

In some cases a sexual act would appear to precede spore formation.

In early inquiries a great point was made of the prevention of putrefaction, and work was done in the way of finding how much of an agent must be added to a given solution, in order that the bacteria accidentally present might not develop. But for various reasons this was an inexact method, and to-day an antiseptic is judged by its effects on pure cultures of definite pathogenic microbes, and on their vegetative and spore forms. Their standardization has been effected in many instances, and a water solution of carbolic acid of a certain fixed 'strength is now taken as the standard with which other antiseptics are compared.

Such cankers often commence in mere insect punctures, frosted buds, cracks in the cortex, &c., into which a germinating spore sends its hypha.

From the germinated spore of a fern plant, which must not be Life his tory.

Referred to a "massive single-player online game", Spore contains elements of several different genres, including simulation, real-time strategy, action, puzzle, and "god" games.

With the full build of Spore, set for release in early January 2008, players will have the opportunity to build their own unique universe.

Spore allows gamers to control the evolution of a species.

Spore will be available as a direct download from EA on that date.
