"Fertilization" Quotes from Famous Books



... continues to grow for a time after their formation, so that they come to be seated in a depression of the upper surface. They are further protected by the growth of the hinder margin of the depression to form a scale-like involucre (in). Fertilization takes place about June, and the sporogonium is fully developed by the winter. The embryo developed from the fertilized ovum consists at first of a number of tiers of cells. Its terminal tier gives rise to the capsule, the first divisions in the four cells of the tier marking ...

New ones could be coined as occasion required. Knowledge would gain by leaps and bounds. There would be a cross-fertilization of cultures.

One would think that Commerce, which has broken down geographical ...

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.

The male and female elements are usually supposed to meet in the outer portion of the Fallopian tubes, fertilization ...

Rotation of crops was practically unknown, and fertilization of the land was rare, although the habitant frequently burned the stubble before putting the plough to his fields. From time to time a part of each farm was allowed to lie fallow, but such fallow fields were left unploughed and soon grew so rank with weeds that the soil ...

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 the ...

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.

... ooegonium. By careful observation the student may possibly be able to follow the spermatozoid into the ooegonium, where it enters the egg cell at the clear spot on its surface. 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 with spines (Fig. 16, F). As these spores do not germinate ...

It is remarkable as an example of trimorphism, the two sets of stamens and pistil being of different lengths in the same flower. Every pistil, in order to affect fertilization, must receive the pollen from the same length in another flower. Professor Darwin experimented with these flowers and wrote about them to Dr. Gray "I am almost stark, staring mad over Lythrum. If I can prove what I really believe, it is a grand case of trimorphism, with three different ...

And even if there was but one, all physiologists agree that there is a variable period in different women, and in the same woman at different times, between insemination and the fertilization of the ovum.

These rapidly expand into "pollen tubes," or filaments, and, penetrating the long style, reach the egg-germs below. Thus cross-fertilization is brought about by the bees which come for the nectar of Salvia. The stalks and outer parts of the flower of this plant produce a very sticky secretion which effectually prevents any small insects from crawling up and helping ...
