"Ova" Quotes from Famous Books
 ... fertilization of the latter. In these cases no fresh accession of sperm-cells was possible, and hence it would seem as if in some birds the female organs were able to store up living sperm-cells, which only work to fertilize and develop ova in the event of some accident rendering it necessary, and which otherwise ultimately lose vitality and ...

... later article on Flustra, made some allusion to a paper read by Darwin before the Linnean Society on a small discovery which he had made by the aid of a "wretched microscope" to the effect that the so-called ova of Flustra were really larvae and had the power of independent action by means ...

... Onesicritus give us; and, provided I be not obliged to believe or justifie all that they say, I could rest satisfied in great part of their Relation: For Pliny[B] tells us, Veris tempore universo agmine ad mare descendere, & Ova, Pullosque earum Alitum consumere: That in the Spring-time the whole drove of the Pygmies go down to the Sea side, to devour the Cranes Eggs and their young Ones. So likewise Onesicritus,[B] [Greek: Pros de tous trispithamous polemon einai tais Geranois (hon kai Homaeron daeloun) ...

... development is predetermined in the fertilised ovum. It is to Weismann that we owe precise and definite conceptions, if not of the nature of heredity, at least of the details of the process. From him we learned to think of the ova or sperms, of the reproductive cells or 'gametes' of an individual, as cells which were from an early stage of development distinguished from the cells forming the organs and tissues; to regard the organism as consisting of soma on the one hand and gametes on the other, both ...

... man—all same yo' callum Baumberga—him come, look, so—" He indicated, by a great craning of neck in all directions, the wariness of one who goes by stealth. "Him walk still all time, go all time ova there." He swept his arm toward the meadows. "Me go still, for watchum. Yo' come, mebbyso make heap much noise—kay bueno. Dat mans, him hear, him heap scare. Me tellum, yo' mebbyso go still." He folded his arms with a gesture of finality, and stood statue-like ...

... shall then go to their aid and succour in fishing after them. Be quiet, said Gymnast, and stir not, my minion. I am now coming to unhang thee and to set thee at freedom, for thou art a pretty little gentle monachus. Monachus in claustro non valet ova duo; sed quando est extra, bene valet triginta. I have seen above five hundred hanged, but I never saw any have a better countenance in his dangling and pendilatory swagging. Truly, if I had so good a one, I would willingly hang thus all ...

... phenomena, defies being crowded into a simple definition. In an animal or plant individual it is expressed by and linked with the ability to produce egg- or sperm-cells (ova or spermatozoa). Sexual reproduction is simply the chain of events following the union of the egg and sperm to produce a new individual. Looked at from another angle, it is that sort of reproduction which requires two differentiated individuals: the male, which produces spermatoza, and ...

... experiments the conclusion is almost forced upon us that, in the types investigated, of the two sexes the female is to be regarded as heterozygous in sex, containing one unpaired dominant element, while the male is similarly homozygous in the absence of that element. (In other words, the ova are each EITHER female, OR male (i.e. non-female), but the sperms are all non-female.) It is not a little remarkable that on this point—which is the only one where observations of the nuclear processes of gameto-genesis have yet been ...

... that it was very destructive to the spawn, at that time supposed to be lying on the sea bottom. But the investigations of the late Professor Sars, for the Swedish Government, into the spawning habits of sea fish, have conclusively revealed the fact that the ova of fish float on the surface of the water during the whole period of their development. Not only have the floating ova of the cod and haddock been reared, but the common plaice, the representative of the flatfish family, including the brill, the sole, and the turbot, is also known to ...

... a Newton or an Einstein, yes." Belle thought for a minute, then grinned at him impishly. "Now watch the brain of a Bellamy perform. Get into high gear, brain.... I wish I knew something about biochemical embryology; but I read somewhere that ova are sterile, so our galaxy is an ovum. Therefore our super-galooper is a gal—which incontrovertible fact accounts for and explains rigorously the long-known truth that women always have been, are now, and always will be vastly superior to men ...

... reproduction is resorted to, and this in a way that illustrates most instructively the differentiation of the female and male cells. Some of the cells are seen accumulating nourishment at the expense of the others and grow larger, and if this continues, cells which must be regarded as ova, or female cells, result; while other cells, less advantageously placed with more competitors struggling to obtain food, grow smaller and gradually change their character, becoming, in fact, males. In some cases distinct colonies may in this way arise, ...

... which, recently excluded from the ova, are still invisible to common eyes; or, at least, are inconspicuous or unobservable. Being weak, in consequence of their recent emergence from the egg, and of extremely small dimensions, they are unable to withstand the rapid flow of water, and so betake themselves to the gentler ...

... barrenness is equally due to a variety of causes. In a number of breeding studs the proportion of sterile mares has varied from 20 to 40 per cent. It may be due to: (a) Imperfect development of the ovary and nonmaturation of ova; (b) cystic or other tumors of the ovary; (c) fatty degeneration of the ovary in very obese, pampered mares; (d) fatty degeneration of the excretory tubes of the ovaries (Fallopian tubes); (e) catarrh of the womb, ...
