When the seven radicles were looked at again, after an interval of 23 h.
The circumnutating movement of the terminal growing part both of the primary and secondary radiclesis so feeble that it can aid them very little in penetrating the ground, excepting when the superficial layer is very soft and damp.
In those cases in which radicles with attached filaments were placed so as to stand up almost vertically, they curved downwards through the action of geotropism, circumnutating at the same time, and their courses were consequently zigzag.
The grease, therefore, slightly checked the growth of the terminal part, but this part was not much injured; for several radicles which had been greased for a length of 2 mm.
Lastly, five other radicles were similarly treated, but were exposed to geotropism during only 45 m.
Phaseolus multiflorus: tracks left on inclined smoked glass-plates by tips of radicles in growing downwards.
Squares of card were attached to one side of the tips of 11 radicles within the same jars in which the above trials were made, and five of them became plainly, and one slightly, curved away from this side.
Four radicleswere allowed to grow downwards over plates of smoked glass, inclined at 70o to the horizon, under the Fig.
Eight of these radicles were afterwards reversed, and again touched with caustic, and none of them became geotropic in 24 h.
With radicles of the bean, when extended horizontally in damp air, geotropism always conquered the effects of the irritation caused by squares of card attached to the lower sides of their tips.
In order that these movements should be properly displayed, it appears necessary that the radicles should grow at their normal rate.
The tips of 13 radicleswere coated with the grease for a length of 2 mm.
The tips of the other eight radicles [page 169] were just touched with dry caustic on one side.
The ether which is so largely used in hospitals for wounded soldiers is ethyl ether, consisting of two ethyl radicles joined by oxygen.
All the ethers are formed by taking two of the paraffin radiclesand linking them together by means of the two hooks of an oxygen atom.
The search for, and the identification of, compound radicles began to occupy the attention of chemists, and a definite line of attack upon organic matter was recognized.
The advocates of each theory sought for evidence in its favor, and so innumerable discoveries were made, compound radicles were recognized in great numbers, and the mass of data became so overwhelming that for a while chaos reigned.
This characterises the so-called diatomic or bivalent reactions of radicles or residues.
Let us suppose that two radicles (simple or compound), whose symbols and combining weights are A and B, combine together, forming a compound composed of x atoms of A and y atoms of B.
If, at the same time, in addition to the substitution of one of the radicles of methane for hydrogen a further exchange of part of the hydrogen for some of the other groups of elements X, Y .
But it seems that other factors may come into play and cause a rearrangement of the radicles which compose it, and this will result in the formation of a unit character different from that to which it would ordinarily give rise.
We further conceive that it is possible for the various radicles which compose these molecules to arrange themselves in various manners, and with each new arrangement a different form of unit character will be developed.
These molecules, then, are built up from radicles derived from both parents, the most stable combinations being formed and one portion of the molecule dominating the whole.
Fourthly, some or all the groups of radicles in each gamete may be united so closely that in the sexual act they do not break up, but enter bodily into the new resulting organism.
We may probably go farther and say, not only will the most stable biological molecules be formed, but the most stable radicles will dominate the molecule.
In order to avoid the manufacture of fresh terms we may speak figuratively of the germ cells as being composed of biological molecules, which in their turn are built up of biological radicles and atoms.
As the effusion of fluid is due to the portal obstruction, it follows that depletion of the terminal radicles of this system will act most directly on the origin of the troubles.
The result of this obliteration of the portal radicles is the impaired nutrition of the lobules and atrophy of the cells.
Ulceration, abscesses, or purulent inflammation occurring at any point within the area of origin of the radicles of the portal vein may induce pylephlebitis and consequent hepatic abscess.
It follows that the minute capillaries emptying into the central vein are also distended with blood, and finally the portal vein and its radicles throughout are similarly affected.
Obstruction of the portal circulation is rather unusual, and the explanation is to be found in the fact that the amyloid degeneration occurs first in the radicles of the hepatic artery.
This milky fluid was noticed by Leroux, who even then expressed his doubts, whether the radicles of the umbilical vein receive blood from the mother, or whether they only serve to absorb a white fluid which resembles chyle.
These loose tufts of venous radicles appear to absorb nourishment for the ovum, much in the same manner as the roots of a plant.
We may liken the plant to the molecule of an organic compound; the root, the stem and the leaves to the compound radicles of which this molecule is built up, and the tissue, fibres, etc.
The conceptions of compound radicles and of substitution held some such position in organic chemistry as that which I have now attempted to indicate when Dumas and Liebig began their work in this field.
From this dualistic view of the molecule there naturally arose a disposition to regard the compound radicles of organic chemistry as the non-oxygenated parts of the molecules of organic compounds.
The caudex is altogether similar in structure to that of Alsophyla, equally furnished with strong black bristly radicles towards its base.
What is the cause of the plurality of radicles in certain species of Lemna, and their blank in others?
This enclosure arises entirely from the excessive tendency to cohesion between the roots and radicles of some of the species of this genus.
There is this certain about them, that they depend on the presence of vascular tissue, from which the radicles or the divisions of each root originate: see young Hyacinth roots, grown in water.
Are the sheaths found on certain radiclesstrictly confined to monocotyledonous plants.
When this takes place, one or more short, brownish, hair-like radicles emerge from one part of the surface (Pl.
The very fine rootlets or radicles of water-plants often show the rotation of the protoplasm very distinctly.
Its radicles resemble pipe-stems, or as they lie stranded on the beach, slightly curved and with the brown tapering calyx tube attached, green snakes with pointed beads.
Whole battalions of living mangrove radicles fall into the rivers during February and March.
It is true that the plant does not react with the rapidity which characterizes the animal; Darwin found that radicles are not sensitive to temporary contact, but only to long, though to slight pressure.
The radicles did not present the appearance of having been subjected to a sufficient pressure to account for their curvature.
At the end of the germination, the radicles have become 1-1/2 longer than the barley, and are contorted so that the corns hook into one another, but the acrospire is just beginning to push through.
Maize, or Indian corn, has also been employed to make beer; but its malting is somewhat difficult on account of the rapidity and vigour with which its radicles and plumula sprout forth.
About a day after the radicles appear, the rudiments of the stem, or of the plumula, sprout forth, called by the English maltsters the acrospire.
In consequence, the radicles tend to increase in length with very great rapidity, and must be checked by artificial means, which constitute the chief art of the maltster.
Venous emboli are those which approach the heart by the peripheral veins of the body or the pulmonary veins, and the liver by the radicles of the portal vein.
It is possible that they may further obtain access into the circulation through the radicles which furnish the communications between the capillaries and the lymphatics.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "radicles" in a variety of sentences. We hope that you will now be able to make sentences using this word.
