- n. The act or process of reproducing, presenting, or yielding again; repetition.
- n. The act or process of restoring parts of an organism that have been destroyed or removed.
- n. Specifically The process whereby new individuals are generated and the perpetuation of the species is insured; the process whereby new organisms are produced from those already existing: as, the reproduction of plants or animals. The reproduction of plants is effected either vegetatively or by means of spores or of seeds. Vegetative reproduction consists in the individualizing of some part of the parent organism. In low unicellular plants this is simply a process of flssion, one cell dividing into two or more, much as in the formation of tissue, save that the new cells become independent. In higher plants this method obtains by the shooting and rooting of some fraction of the organism, as a branch, a joint of a rootstock, in Begonia even a part of a leaf; or through specially modified shoots or buds, as the gemmæ of some algæ, mosses, etc., the bulblets of some mosses, ferns, the tiger-lily, etc., the corms, bulbs, and tubers of numerous annual plants. The cells engaged in this mode of reproduction are simply those of the ordinary tissues. Very many, but not all, plants propagate in this manner; but all are capable of reproduction in other methods Included under the term spore-reproduction, which is reproduction most properly so called This is accomplished througn special reproductive cells, each of which is capable of developing into an individual plant. These are produced either independently, or through the conjunction of two separate cells by which their protoplasm coalesces. These may also in a less perfect sense be called reproductive cells. Reproduction through the union of two cells is sexual; through an independent cell, asexual. Sexual reproduction proceeds either by conjugation (that is, the union of two cells apparently just alike, which may be either common vegetative cells or specialized in form) or by fertilization, in which a smaller but more active sperm-cell or male cell impregnates a larger, less active germ-cell or female cell. In cryptogamous plants both methods are common, and the reproductive cells are termed spores, or when of the two sexes gametes, the male being distinguished as antherozoids, the female as oöspheres. In flowering plants spore-reproduction is always sexual, fertilization becoming pollination, the embryo-sac in the ovule affording the female cell and the pollen-grain the male cell. But the union of these cells produces, instead of a detachable spore, an embryo or plantlet, which, often accompanied by a store of nutriment, is inclosed within an integument, the whole forming a seed. The production of seeds instead of spores is the most fundamental distinction of phanerogams. Spore-reproduction is consummated by the germination of the Spore or seed, which often takes place after a considerable interval.

“That with the increased productiveness of labour there is increased facility for the reproduction of machinery required for the production of water, light, fuel, and food; and that this diminution in the cost _of reproduction_ is attended with a constant diminution in the value of all such machinery previously accumulated, and diminution in the proportion of the product of labour that can be demanded as rent for their use; and thus, while labour steadily increases in its power to yield commodities of every kind required by man, capital as steadily diminishes in its power over the labourer.”
“Thus it is possible to speak of physical parenthood and of psychical parenthood, and thus not only to avoid the term reproduction, but to get better value out of its substitutes.”
“Now if we can all have the same protection in reproduction, then we would eliminate these wedge issues meant to distract from real issues. come together lyrics”
“Now if we can all have the same protection in reproduction, then we would eliminate these wedge issues meant to distract from real issues.”
“She said the moral right of women to make decisions about reproduction is essential for them to be recognized as human beings and while she respects the "category of fetal life," she doesn't "have a sense of individual fetuses as possessing high value.”
“Bucks skylarked with bucks or flirted with the maidens, while the older squaws, shut out from this by virtue of having fulfilled the end of their existence in reproduction, gossiped as they braided rope from the green roots of trailing vines.”
“Will email in case you have a way. the reproduction is not perfect but it illustrates the layout”
“One of the discoverers of the structure of DNA, Francis Crick, credited What Is Life? as a theoretical description, before the actual discovery of the structure of DNA (the existence of the molecule had been known for nearly 2 decades, but its role in reproduction and its helical shape had not even been guessed at this time), of how genetic storage would work and a source for inspiration for the initial research.”
“Sexual selection theory argues that females invest more heavily in reproduction than males and thus tend to be choosier in terms of matechoice.”
“But what if, among Time Lords, reproduction is like a metacrisis?”
