Quotes & Sayings About Cell Theory

We may regard the cell quite apart from its familiar morphological aspects, and contemplate its constitution from the purely chemical standpoint. We are obliged to adopt the view, that the protoplasm is equipped with certain atomic groups, whose function especially consists in fixing to themselves food-stuffs, of importance to the cell-life. Adopting the nomenclature of organic chemistry, these groups may be designated side-chains. We may assume that the protoplasm consists of a special executive centre (Leistungs-centrum) in connection with which are nutritive side-chains... The relationship of the corresponding groups, i.e., those of the food-stuff, and those of the cell, must be specific. They must be adapted to one another, as, e.g., male and female screw (Pasteur), or as lock and key (E. Fischer). — Paul R. Ehrlich

For a long while, Norby had harbored a theory that places acted like dry-cell batteries, storing remnants of the lives of everyone who had ever passed through them. — Craig Lancaster

Cell genetics led us to investigate cell mechanics. Cell mechanics now compels us to infer the structures underlying it. In seeking the mechanism of heredity and variation we are thus discovering the molecular basis of growth and reproduction. The theory of the cell revealed the unity of living processes; the study of the cell is beginning to reveal their physical foundations. — C.D. Darlington

If we examine the accomplishments of man in his most advanced endeavors, in theory and in practice, we find that the cell has done all this long before him, with greater resourcefulness and much greater efficiency. — Albert Claude

It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism — Dennis Flanagan

You know the theory of cell irritability?. If you take an amoeba cell and poke it a thousand times, it will change and then re-form into its original shape. And then, the thousandth time you poke this amoeba, the cell will completely collapse and become nothing. That's kind of what it's like being famous. People say hi, how are you doing, and after the thousandth time, you just get angry; you really pop. — Bill Murray

It is hard for anyone who has not given himself wholeheartedly to a belief (and I say again, Miss V., that is how it is: you give yourself to it, it does not fall upon you like sanctifying grace from Heaven) to appreciate how the believer's conscious mind can separate itself into many compartments containing many, conflicting, dogmas. These are not sealed compartments; they are like the cells of a battery (I think this is how a battery works), over which the electrical charge plays, leaping from one cell to another, gathering force and direction as it goes. You put in the acid of world-historical necessity and the distilled water of pure theory and connect up your points and with a flash and a shudder the patched-together monster of commitment, sutures straining and ape brow clenched, rises in jerky slow motion from Dr. Diabolo's operating table. — John Banville

The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral. — Ernst Haeckel

If biologists have ignored self-organization, it is not because self-ordering is not pervasive and profound. It is because we biologists have yet to understand how to think about systems governed simultaneously by two sources of order, Yet who seeing the snowflake, who seeing simple lipid molecules cast adrift in water forming themselves into cell-like hollow lipid vesicles, who seeing the potential for the crystallization of life in swarms of reacting molecules, who seeing the stunning order for free in networks linking tens upon tens of thousands of variables, can fail to entertain a central thought: if ever we are to attain a final theory in biology, we will surely, surely have to understand the commingling of self-organization and selection. We will have to see that we are the natural expressions of a deeper order. Ultimately, we will discover in our creation myth that we are expected after all. — Stuart A. Kauffman

You know, in America, Christian fundamentalism vs. science. You know, be it teaching Darwinian evolutionary theory or stem cell res- You know, the whole thing, and then the issue of women being educated in Middle Eastern - I mean, it just seems so contemporary. In terms of spirituality, it's interesting because I actually think (her character in Agora) Hypatia is very spiritual. — Rachel Weisz

General Systems Theory, a related modern concept [to holism], says that each variable in any system interacts with the other variables so thoroughly that cause and effect cannot be separated. A simple variable can be both cause and effect. Reality will not be still. And it cannot be taken apart! You cannot understand a cell, a rat, a brain structure, a family, a culture if you isolate it from its context. Relationship is everything. — Marilyn Ferguson

Among other members of our cell I remember Dr. Wilhelm Reich, Founder and Director of the Sex-Pol. (Institute for Sexual Politics). He was a Freudian Marxist; inspired by Malinowski, he had just published a book called 'The Function of the Orgasm,' in which he expounded the theory that the sexual frustration of the Proletariat caused a thwarting of its political consciousness; only through a full, uninhibited release of the sexual urge could the working-class realize its revolutionary potentialities and historic mission; the whole thing was less cock-eyed than it sounds. — Arthur Koestler

The extracellular genesis of cells in animals seemed to me, ever since the publication of the cell theory [of Schwann], just as unlikely as the spontaneous generation of organisms. These doubts produced my observations on the multiplication of blood cells by division in bird and mammalian embryos and on the division of muscle bundles in frog larvae. Since then I have continued these observations in frog larvae, where it is possible to follow the history of tissues back to segmentation. — Robert Remak

The cause of nutrition and growth resides not in the organism as a whole but in the separate elementary parts - the cells. — Theodor Schwann
