As this is not the incorporation of either into the living sobstance, but is only its manufacture into the complex substances which we find in the plant, it seems preferable to limit the term assimilation to the processes by which foods are actually taken into the protoplasm.
The other constructive processes, which arc dependent partly upon the oxidation of the carbohydrates so formed and therefore upon an expenditure of part of such energy, also mar]~ the storage of energy in the potential form.
But in addition to bringing forward a fundamental and philosophical view of morbid processes, which probably contributed more than any other single cause to vindicate for pathology the place which he claimed for it among the biological sciences, Virchow made many important contributions to histology and morbid anatomy and to the study of particular diseases.

But whilst all the organic processes in man go on mechanically, and though by reflex action he may repel attack unconsciously, still the first affirmation of the system was that man was essentially a thinking being; and, while we retain this original dictum, it must not be supposed that the mind is a mere spectator, or like the boatman in the boat.

This serves a double purpose, bringing up from the soil continually a supply of the soluble mineral matters necessary for their metabolic processes, \vhich only enter the plant in solutions of extreme dilution, and at the same time keeping the plant cool by the process of evaporation.
Even in the higher flowering plants, in which the processes of the absorption of substances from the environment has been most fully studied, there is a stage in their life in which the nutritive processes approximate very closely to those of the group last mentioned.
The muscle-fibres arise as processes from the bases of the epithelial cells; such cells may individually become sub-epithelial in position, as in the polyp; or, in places where muscular tissue is greatly developed, as in the velum or sub-umbrella, the entire muscular epithelium may be thrown into folds in order to increase its surface, so that a deeper sub-epithelial muscular layer becomes separated completely from a more superficial bodyepithelium.
These processes have been studied in detail by A.
The various grades of life on our planet are the natural consequences of certain physical processes involved in the gradual transformations of the earth.
From this point of view the processes of nature from the inorganic up to the most complex of the organic become stages in the self-realization of nature.
All these processes are regarded as a series of manifestations of a vital principle in higher and higher forms. Oken, again, who carries Schelling's ideas into the region of biological science, seeks to reconstruct the gradual evolution of the material world out of original matter, which is the first immediate appearance of God, or the absolute.
BM- Within quite recent years, however, a special school q Y P has arisen with the main object of treating the processes of evolution quantitatively.
The statute is aimed at appeals; but the words used in it concerning " citations and all other processes " are wide enough to take away also the " original " jurisdiction of the pope.
An exact and conscientious worker, he did much to improve and systematize the processes of analytical chemistry and mineralogy, and his appreciation of the value of quantitative methods led him to become one of the earliest adherents of the Lavoisierian doctrines outside France.
The organism is largely dependent for its vital processes upon gaseous interchanges.
There is no need for cuticularization here, as the external dangerous influences do not reach the interior, and the processes of absorption which Boussingault attributed to the external cuticularized cells can take place freely through the, delicate cell-walls of the interior, saturated as these are with water.
What is not used in the constructive processes is employed in the evaporation of the water, the leaf being thus kept cool.
These respiratory processes are associated with the liberation of energy by the protoplasm, energy which it applies to various purposes.
First are the inefficiencies in the natural processes of agriculture.
Similarly, our agricultural processes aren't so hot.
As technology improves, all these processes and systems will improve and also fall in price.
His prestige as a minister, already injured by these two blows, suffered further during the autumn and winter from the cattledriving agitation in Ireland, which he at first feebly criticized and finally strongly denounced, but which his refusal to utilize the Crimes Act made him powerless to stop by the processes of the "ordinary law"; and the scandal arising out of the theft of the Dublin crown jewels in the autumn of 1907 was a further blot on the Irish administration.

Eventually he was able to prove that the biological doctrine of omnis cellula ecellula applies to pathological processes as well as to those of normal growth, and in his famous book on Cellular-pathologic, published at Berlin in 1858, he established what Lord Lister described as the "true and fertile doctrine that every morbid structure consists of cells which have been derived from pre-existing cells as a progeny."
Materia, matter), in philosophy, the theory which regards all the facts of the universe as explainable in terms of matter and motion, and in particular explains all psychical processes by physical and chemical changes in the nervous system.

The muscular tissue consists primarily of processes from the bases of the epithelial cells, processes which are contractile in nature and may be distinctly striated.
A further stage in evolution is that the muscle-cells lose their connexion with the epithelium and come to lie entirely beneath it, forming a sub-epithelial contractile layer, developed chiefly in the tentacles of the polyp. The of the evolution of the ganglioncells is probably similar; an epithelial cell develops processes of nervous nature from the base, which come into connexion with the bases of the sensory cells, with the muscular cells, and with the similar processes of other nerve-cells; next the nerve-cell loses its connexion with the outer epithelium and becomes a sub-epithelial ganglion-cell which is closely connected with the muscular layer, conveying stimuli from the sensory cells to the contractile elements.
