... while in the male there is one odd one, the remaining 20 being like the corresponding 20 of the female. Before the germ cell becomes fit to mix with a germ cell of opposite sex, in the process of fertilization, it must lose one half of these. So the number of chromosomes for the species is kept the same or constant. This is the process of maturation. In the process, when the chromosome number is halved among ...

... had a solidarity of its own with national tendencies.[29:1] On the tide of the Father of Waters, North and South met and mingled into a nation. Interstate migration went steadily on—a process of cross-fertilization of ideas and institutions. The fierce struggle of the sections over slavery on the western frontier does not diminish the truth of this statement; it proves the truth of it. Slavery was a sectional trait that would not down, but in the West it could not remain sectional. It was the greatest of frontiersmen ...

... for cultivation of hickories has been worked out only with the pecan up to the present time. With this species, it has been determined that clean cultivation with plenty of fertilization gives best results, as with apples. It is probable that Stringfellow's sod culture method will come next in order, and will perhaps be most generally used by nut orchardists, because it is less expensive and requires less labor. The sod culture method includes the idea of cutting ...

... genus, in which the end of the spadix was prolonged into a very long, thread-like appendage thrown over the leaves of the plant or of its neighbors, and ultimately reaching the ground, and thus, it is presumed, affording ants and other insects means of access to the flowers, and consequent fertilization. These species were grown by Mr. Elwes, and exhibited by him before the Scientific Committee. The present species is of somewhat similar character, but is, we believe, new alike to gardens and to science. We met with it in the course of ...

Her remembrances of home and childhood were remembrances of the drying up of every spring and fountain in her young heart as it gushed out. The golden waters were not there. They were flowing for the fertilization of the land where grapes are gathered from thorns, and figs ...

... kinds of cover crops which may be used in the apple orchard will be considered in the next chapter as they are so closely associated with fertilization. Strictly speaking, however, a cover crop is used principally to secure its mulching and physical effects on the soil in the intervals between the seasons of tillage. In addition to its physical and feeding effects the cover crop serves to check the growth of trees in the latter part of the ...

... the soil in a state of fertility depends primarily upon fertilization. The obtaining of fertilizers is, accordingly, for future society also one of the principal tasks.[200] Manure is to the soil what food is to man, and just as every kind of food is not equally nourishing to man, neither is every kind of manure of equal benefit to the soil. The ...

... large garden varieties are rarely self-pollinated, even if left uncovered, but the chances of fertilization with inferior kinds, generally the most abundant pollen producers, are so great that it is well to protect all seed-bearing blooms from insect interference. If the work is to be done on a large scale sleeves of netting or muslin large enough to enclose ...

... into the womb. After they have arrived in the womb they are, as a rule, cast off with the secretion and leave the body. If in the course of its travel from the ovaries, through the tube to the womb, the female ovum or egg meets with the male elements, fertilization or impregnation may take place. If then it is not cast off it generally lodges in the womb and pregnancy has begun. The male and female elements are usually supposed to meet in the outer portion of the Fallopian tubes, fertilization then taking place; but this can occur any place from the ovary ...

... insensate, we find the universal law of sex-attraction and repulsion. The pollen from an oak tree, for example, may be blown about by the wind and may light upon a plant which is far removed in species from its own; but if such be the case, no fertilization takes place. The fundamental law of Love is to attract to itself its own; that which belongs to it by right of Cosmic ...

... The whole country becomes a lake from which the villages, built on eminences, emerge like little islands. The water recedes in September; by December it has returned to its proper channel. Everywhere has been left a fertile, alluvial bed which serves the purpose of fertilization. On the softened earth the peasant sows his crop with almost no labor. The Nile, then, brings both water and soil to Egypt; if the river should fail, Egypt would revert, like the land on either side ...

... large nor so well coloured as the first, but still fertile eggs that were duly hatched. But for the removal of the first set, these subsequent eggs would never have been developed or laid. Now, the theory has always been that the contact of the sperm- and germ-cells causes the development and 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 ...

... closed off to the roots of another. Gardeners who use close plantings and intensive raised beds often unknowingly bump up against this limiting factor and are disappointed at the small size of their vegetables despite heavy fertilization, despite loosening the earth two feet deep with double digging, and despite regular watering. Thought about in this way, it should be obvious why double digging improves growth on crowded beds by increasing the depth to ...

... even the perfumes of flowers may be said to be of sexual character. They are given out at the reproductive period in the lives of plants, and they clearly have very largely as their object an appeal to the insects who secure plant fertilization, such appeal having as its basis the fact that among insects themselves olfactory sensibility has in many cases been developed in their own mating.[54] There is, for example, a moth in which both sexes are similarly and inconspicuously marked, but the males diffuse ...

May not these substances be traces left within him of the passage of the electric fluid which is the principle of all fertilization? Would not electricity manifest itself by a greater variety of compounds in him than in any other animal? Should not he have faculties above those of all other created beings for the purpose of absorbing fuller portions of the Absolute principle? and may he not assimilate that principle ...

Israel was never left to settle down again into provincialism, but was stirred by the currents of the great world of thought that poured in upon her from Greece and Egypt, from Rome and the far East. "A cross-fertilization of ideas" was thus carried on by Providence. The result of grafting the richest varieties of thought upon such a sturdy stock could not fail of proving something rare and rich. As was natural from such conditions, the thought of the nation took on ...

... the new strain will be kept constant in this way. This method of using the seed for reproducing the plant is called the sexual method, because two parents cooeperate in the production of the seed. The pollen came from one parent and the ovule, which after fertilization swelled up into the seed, came from another. By this combination of two individuals new varieties become quite possible. Nature seems to be more concerned in improving her strain than in maintaining her older strains. In all of ...

... them the spermatozoa. In the higher animals there is a further development, and special organs are evolved to ensure the conjunction of the two elements. I have not space to describe in detail the effect of this union of the two cells, generally spoken of as fertilization. It may be found fully recorded step by step in any biological manual. Very briefly, the sperm-cells, which are active, freely moving units, swarm round the egg-cell and one of them eventually enters it. The essential part ...

The wonderful adaptations of many flowers and insects to each other, as to the fertilization of the former, and as to the life of the individual insect and the propagation of its kind, are evidence of design. For example, there are certain species of plants that are dependent for their fertilization on certain species of ...

Now, the question of the existence of this water supply at a uniform depth beneath the earth's surface can be proved by noting the existence of the springs that we know of, that have found their way without artificial aid ...

Hirase and Ikeno, whose discoveries of spermatozoids in Ginko and Cycas have no little value for botanists, especially in the development of the theory of certain forms of fertilization. These instances show that the faculty of original thought is not entirely lacking among the Japanese. Under favorable conditions, such as now prevail, there is good reason for holding that the ...

If a phrase will do instead of an explanation, we may sum them up, with the brilliant French psychologist, Tarde, as "a cross-fertilization of imitations." We need not, however, go far to get an impression of how this process of change works. It is going on every day in our midst under the name of "change of fashion."

The scales which form the female catkin are of a whitish green; the bractea on the back is slightly reddish on its upper side; and the stigma, which has two points, is of a bright red. After fertilization, the scales augment in thickness; and, becoming firmly pressed against each other, they form by their aggregation a fruit, which is three years before it ripens. During the first year it is scarcely larger than the female catkin; and during the second year it becomes globular, and ...

As a result of the entrance of the spermatozoid (fertilization), the egg cell becomes surrounded by a thick brown wall, and becomes a resting spore. The spore loses its green color, and the wall becomes dark colored and differentiated into several layers, the outer one often provided ...
